Ida Rolf on The pelvic floor

The pelvic floor, in Ida's teaching, is not a patch of muscle to be palpated and freed — it is the operative result of everything else the practitioner has done. By the time she was teaching the advanced classes of the mid-1970s, she had stopped letting students name the pubococcygeus as the answer to questions about the fourth hour and started insisting that the floor is determined by the sacroiliac joint, the lumbosacral junction, the adductors, the coccyx, and the rotators — by the architecture above and below it, not by the sling itself. The pubococcygeus is the key, but only because it registers what the rest of the pelvis is doing. This article draws on her advanced-class transcripts from 1971 through 1976 — Boulder, Big Sur, Santa Monica, IPR — together with the anatomical lectures of her colleague Tom Wing, to show how she taught the floor as the meeting point of three doctrines: that everything must be suspended rather than rested; that the floor is reached through its neighbors; and that the coccyx, not the pubes, is the indicator of whether the work has landed.

The question Ida kept asking in the fourth hour

In the public-tape teaching of the early 1970s, Ida walked her class through a fourth-hour body and then stopped to interrogate them. The pelvis was the goal of the hour, she said. They had been working the medial line of the legs, the adductors, the thickened tissue along the inner thigh. Why? What were they actually trying to accomplish? She rejected the obvious answer — verticality, gravity-line — and demanded an answer in terms of physiology. The exchange that followed is the clearest single statement she ever made of what the fourth hour is for, and it begins not with the muscle she finally names but with the question she refuses to let students answer too quickly. The pedagogy is deliberate: she wants the students to find the pelvic floor the way the work itself finds it — by being chased there through the supporting structures, not by being aimed at directly.

"And, basically, the key of the pelvic floor is the pubococcigeus."

From the RolfB3 public tape, Ida pressing the class on the physiology of horizontalizing the pelvis:

The Socratic moment where Ida refuses generalities and forces the class to name the pubococcygeus as the key of the floor.1

What's striking about this exchange is how late in the reasoning the pubococcygeus arrives. Ida pushes the class through several wrong frames first — gravity, viscera resting on the floor — before settling on the language of integrity and support. The floor isn't a shelf the organs sit on. It's a sling whose tone determines whether the organs hang at all. That distinction will organize everything else she says about the structure across the rest of her advanced-class teaching.

Nothing rests — the doctrine of suspension

Immediately after naming the pubococcygeus as the key, Ida pivots to a larger doctrine that she considered the conceptual divide between her practice and conventional anatomy. The viscera, in her teaching, must not rest on the pelvic floor. The floor must not rest on anything. The body as a whole is a suspension structure, not a stack. This is a claim she made in many places and many ways across the corpus, but the passage that follows is the most direct statement of it specifically with regard to the pelvis. She frames it explicitly as the place where her thinking parts company with the medical anatomy textbooks the students have been schooled on, and she anticipates that they will be pulled back toward the resting-on-the-floor frame by every other source they encounter.

"Everything must be suspended somewhere. Now this is going to be the difference in your thinking and the thinking that's going to overwhelm you on every side from these other well meaning and, in our own opinion, well informed people because they know that gravity's always pulling everything down. Everything has to rest on something. It just ain't so. If you organize the field of force, it doesn't rest. It swims."

In the same RolfB3 lecture, Ida draws the line between her view and the conventional one:

The doctrine of suspension stated as a structural principle, with Ida warning the class that conventional thinking will pull them the other way.2

The phrase she uses — *they swim* — is worth keeping in mind. It is the image around which her whole pelvic-floor doctrine organizes itself. A swimming organ is one whose position is held by the balance of forces around it, not by the strength of a shelf beneath it. The practitioner's job in the fourth hour is not to reinforce the shelf but to organize the field so the swimming becomes possible. Whether the pubococcygeus can hold its tone is the readout of whether the field is organized.

"When the pubococcygeus is balanced, then you get the kind of balancing of forces, of physiological forces within that body, which enables this to happen, and it doesn't rest. Now the story of how this has been developed in the medical concept is an interesting one."

Continuing in the same passage, on what balance of the pubococcygeus actually achieves:

States the positive case — when the floor is balanced, the suspension actually happens and the organs no longer rest.3

She follows this with a brief biographical aside about Dr. Arnold Kegel, the Los Angeles physician who in the 1940s and 50s worked on postpartum incontinence and eventually identified the pubococcygeus as the relevant muscle. For Ida, Kegel's story is illustrative — even a sympathetic clinician working on the right structure could only see it functionally, as a contractile sling to be exercised. Her contribution, as she frames it, is to see the muscle as a structural indicator of how the whole pelvis is organized. The exercise model isolates; the structural model integrates.

What actually determines where the floor is

Having named the pubococcygeus as the key, Ida then does something that surprises students every time: she takes the muscle back. In the RolfB4 public tape she walks the class through a sequence that is the structural mirror image of the one she just delivered. The pubococcygeus is the muscle, yes — but the position of the floor is not determined by the muscle. It is determined by the joints above it. The lumbosacral articulation, the joint between the fourth and fifth lumbars, the sacroiliac joint — these are what fix where the floor sits. Shift any of those lumbars and you shift the floor. This is the teaching beat that the rest of the article will build on: the floor is the consequence of its supports, and the practitioner reaches it by working everywhere except on it.

"Now realize what determines where the pelvic floor is. It's not those half dozen muscles which we named the other day as being the pelvic floor. Not at all. It's the sacroiliac articulation. It's the articulation between the fifth lumbar and the sacrum. It's the articulation between the fourth lumbar and the fifth lumbar."

In the RolfB4 lecture, after a long detour through epistemology, Ida returns to the pelvic floor:

The cleanest single statement Ida ever gives of what actually determines pelvic-floor position — the joints, not the muscles.4

She follows this with examples of habitual postures that disorganize the floor: athletic training that shortens the hamstrings without working their antagonists; postures that spread the knees and shorten the adductors; the cumulative effect of how a child learned to stand and walk. Each of these is named as a way of altering the floor without ever touching it. The practitioner's response, by symmetry, is to work the lumbars, the hamstrings, the adductors, the ankle-knee line — and let the floor follow. The chain is causal in both directions: bad postures travel down into the floor; good work travels up from the periphery into the floor.

"See what I'm telling you? Just as soon as you shift any of those lumbars back on any of those lumbars, you're going to get a different relationship in that pelvic floor. Just as soon as you take on the type of athletic training which shortens and tightens the hamstrings to the exclusion of the antagonists of the hamstrings, you're going to interfere with that pelvic floor. Just assume as you do any of these habitual postures that spread the knees wide, thereby shortening the brassless and altering the hamstring relationship in there, you're going in feel that pelvic floor. So if there is a vast terror incognito in there for each and every individual about how he developed these various physical attitudes and therefore mental attitudes."

Continuing the same lecture, Ida enumerates the ways daily habit deforms the floor:

Concrete examples of how the floor's position is set by everything above and below it — the chain of disorganization travels in both directions.5

The medial line is the road; the floor is the destination

In a 1976 Boulder advanced class, a student named Fritz tried to summarize the fourth hour for Ida and she pressed him to be more precise. The fourth hour is in terms of the pelvis, he said — lengthening the medial line of the body and the pelvic floor. Ida cut him off. There is no *and the pelvic floor*. The medial line and the floor are not two goals; the floor is the end point of the medial-line road. This is one of the clearest pedagogical moments in the corpus, because she is using the grammar of the student's own sentence to teach the doctrine. The word *and* is wrong because it implies the floor is a separate target. The floor is what happens when the medial line is established. Walk the road and you arrive.

"If you really establish the medial line of the body, you will have established the pelvic floor. Quite true, the pelvic floor is your goal, but it's not a separate goal. It's just the end point of a road."

From the RolfA2 public tape, Ida revising Fritz's summary in real time:

The single clearest statement that the floor is reached through its supports, not as a separate target — and that the medial line is the road to it.6

The road-and-endpoint metaphor is one Ida used in several places, and it captures the structural logic of her fourth hour precisely. The medial line is what you can work — the adductors, the ramus of the ischium, the fascia along the inside of the thigh, the attachments at the pubes. The floor is what happens when that work succeeds. To go after the floor directly is to misunderstand the geometry. You cannot, with your hands, organize a pelvic floor from below; you can only organize the structures that determine its position, and then watch the floor reorganize.

"Well the fascia that wraps the adductors and the inside of the leg extends right up inside the pelvis and covers the What do you mean by inside the pelvis? It comes up between the rami and then blends with the fascia that covers the obturator internus and becomes part of the floor of the pelvis. So by releasing the legs you change the tone of the floor of the pelvis. You're on the way, I think. You haven't quite made it. You should've made it more now than anyone else. I would think that also that fascia then in turn blends with the iliac fascia and distal. That's a really good picture in Grants of that."

From the mystery tapes of 1971-72, a student finally answers Ida's question about why the fourth hour matters:

The anatomical mechanism by which the adductor work in the fourth hour reaches the floor of the pelvis — the fascial continuity from leg to obturator internus to floor.7

Tom Wing, the anatomist who lectured to Ida's advanced classes, made the same anatomical case in more systematic detail. In his August 1974 lecture to the IPR class he traced the fascial continuities of the inner pelvis — the obturator internus fascia continuous with the fascia of the pelvic diaphragm, the tendinous arch of the pelvic diaphragm at their meeting, the further continuities with the piriformis fascia, the iliac fascia, the transversalis fascia, and ultimately the fascia lata and the pectineus fascia. The lecture is dense and technical but the point is the one Ida's pedagogy depends on: there is no fascial discontinuity between the inner thigh and the floor of the pelvis. Work in either reaches the other.

The anatomical architecture — Tom Wing's lecture

Ida's classes typically included anatomical lectures by a physician colleague, and in the August 1974 IPR class that role was filled by Tom Wing. His talks survive on tape and provide the formal anatomical scaffolding for Ida's structural claims. His description of the pelvic floor is worth quoting at length because it specifies what Ida tended to leave implicit: that the floor is a compound of two diaphragms, that one of them is incomplete, and that the fascial continuities running through the region are what make the structural-integration approach to the pelvic floor coherent in the first place.

"I think it's what certainly in the general population we usually think of as the pelvis and we forget this deep part here which is the part we're of course most concerned in with because that's where the pelvic floor is. Starting up here then, we would have the whole internal lining of iliac bone aligned by the iliac fascia which is of course going over the iliacus and also covering the psoas. This is going to be continuous with the transversalis fascia of the transversus muscle up in the abdominal region. It will also, as I indicated in the brief talk last time, be continuous with that fascia of the quadratus lumborum. It will be continuous below and posterior with the fascia of the piriformis, which is coming from the sacrum. It will be continuous with the fascia of the iliacus, the obturator fascia. And then by the attachment of the combination of the tendon of the iliacus and the psoas, of the iliopsoas tendon be continuous with the fasciata. And also probably, yeah, would be from the side continuous with the fascia of the pectineus. So actually, we may never, Tom did to me the other day, but frequently in the first ten hours we don't get to the iliac fascia."

Wing tracing the fascial continuities of the inner pelvis:

The systematic anatomical scaffolding for Ida's claim that the floor is reached through the leg, the abdomen, and the lumbar — the fasciae are continuous.8

Wing then moves to the floor proper and distinguishes the pelvic diaphragm — the pubococcygeus, ischiococcygeus, and coccygeus — from the urogenital diaphragm beneath it. The distinction matters because students were tending to collapse the two structures together and to assume the floor was a single sheet. Wing's anatomy is more layered: a complete diaphragm above, an incomplete one below, with the ischiorectal fossa filled with fat between them, and a perineum divided into anterior and posterior triangles.

"Okay, gone further into the pelvis, going down then into the deeper part of the pelvis and down to what we call, I think the floor of the pelvis or what is more frequently in books called the diaphragm of the pelvis. This then, of course, consists of the muscles, the pubococcius, ischio coccyxus, and the coccyxus. Now, are crossing the pelvis from the inner rim of the anterior part of the pubic bones, from this part back here by the spine of the ischium and then from the surface of the obturator fascia which is filling this part across the obturator canal. So that you have this floor of these muscles which then goes back and attaches onto the, I think it's the segment of the coccyx. Now the fascia then, this is going to divide the obturator fascia because the obturator fascia then will be continuous, the upper part, superior part of the obturator fascia will be continuous with that fascia covering the pelvic diaphragm. So the superior fascia of the pelvic diaphragm will be continuous with the superior fascia of the obturator in turnus and that then is actually forming the lateral wall of this pelvic bowl or whatever is another term for it which I can't remember. Then the lower part, the inferior fascia covering the inferior border of these three muscles will be continuous with the lower fascia of the obturator internus. All just talking about the internus."

Wing on the muscles that compose the floor proper:

The technical anatomy of the floor — pubococcygeus, ischiococcygeus, coccygeus, and their attachments — given alongside Ida's structural claims about it.9

What Wing's lecture supplies, and what Ida's teaching depends on, is the proof that the fascia of the inner thigh is continuous with the fascia of the floor. Without that continuity, Ida's claim that adductor work organizes the pubococcygeus would be a metaphor. With it, the claim is mechanical: the practitioner's hand on the adductor is also, fascially speaking, on the floor — at one remove and across the obturator membrane, but on it nonetheless. The fourth hour's geometry depends on this continuity.

The coccyx as indicator

If the pubococcygeus is the key to the floor, the coccyx is the key to the pubococcygeus. The muscle inserts onto the coccyx; its tone is partly determined by where the coccyx sits. In her sixth-hour teaching in the RolfB6 public tape, Ida raised the coccyx from the status of forgettable vestigial bone to the status of structural indicator and made the case at some length. She framed it as a deliberate correction of medical orthodoxy: physicians, she said, treat the coccyx as unimportant — break one and you suffer for a while and recover — but in her structural model the coccyx is one of the body's most consequential indicators because it tells you what the floor is doing and because it gears into the autonomic ganglia.

"changed. A coccyx is a very important, a very significant indicator of what's going on. And I called your attention the other day to the fact that one of the reasons why the coccyx is such an important indicator is because it gears into the nervous system by virtue of the placement of the gang of infarct. Now the coccyx is also this very important member of the body by virtue of the fact that it is the anchorage for the pubococciatus."

From the RolfB6 public tape, Ida raising the status of the coccyx:

Ida's most direct argument that the coccyx is the indicator the practitioner reads to know whether the floor is organized.10

She follows this with a practical claim that students often heard her make: that the integrity of the coccyx-sacrum-ischial-tuberosity triangle determines whether the practitioner can balance the pelvis at all. The fourth hour can do excellent work on the medial line and still fail to deliver a horizontalized pelvis if the coccyx is askew. The sixth hour, which works the rotators and the sacrum from the back, is the place where the coccyx has to be organized definitively. Ida treated this as a non-negotiable diagnostic: look at the coccyx, and you know whether the work has landed.

"What they're really saying is, I forgot about it, but you're reminding me of it. And what I'm trying to bring up to more nearly the surface of consciousness is that without that kind of an organization that you have no way of horizontalizing the pelvis. Look at it in terms of horizontalizing of the floor there and you see how this is knocked askew. You can't horizontalize the floor because the coccyx is askew. And the coccyx determines the floor of the pelvis. Well, it's quite true, it's the second segment of the coccyx, as I remember. In other words, it's way high and the floor of the pelvis doesn't follow as far askew as the coccyx itself goes as your fingers tell you. But all of this is a very important consideration for you that to get in there, you have to get to the ligaments that relate the coccyx, the sacrum, and the STI. Now this is a little bit of a terrifying business to you junior people. That's a terrible long way to be into a person. And it's a scary way."

From the 1971-72 mystery tapes, on the depth required to reach the coccyx-sacrum-ischial-tuberosity organization:

Names the practical and emotional difficulty of working at the depth required to reach the ligamentous attachments of the coccyx — and refuses to soften the requirement.11

In the 1975 Boulder advanced class she returned to this point and made it the test by which a horizontal pelvis is defined. The line connecting the second segment of the coccyx with the pubes is the line that must approach horizontal. To bring that line into position usually requires both lifting the pubes and dropping the coccyx — and dropping the coccyx, she emphasized, is not done at the coccyx. It is done by bringing the lumbars back, by releasing the sacrum from the hip bone, by working the inside line of the leg, by establishing the calcaneus on straight. Each of these moves drops the coccyx by changing what supports it.

Reading horizontality from the coccyx and the pubes

In the seventh-day session of her 1975 Santa Monica advanced class, with Norman, Steve Weatherwax, and the rest of the senior students around her, Ida turned the diagnostic question into a Socratic exercise. How do you define a pelvis as horizontal? She pressed for a precise answer. The tubes and the second segment of the coccyx, a student offered. She accepted that and added the practical version — the underpants don't slant down. From that definition she walked the class through what the practitioner must do to bring the line into horizontal: usually lift the pubes, usually drop the coccyx. The exchange that follows is a working seminar on how to drop a coccyx without touching it.

"But you see, if you are going to define the horizontality of the pelvis as the line connecting the second segment of the coccyx with the pubes. Now look at it in the book. You're going to have to do one of two things or maybe two of two things. You're going to have to probably lift the pubes and drop the coccyx. Chances are that neither of them will be where they belong. How do you drop the coccyx? Come on now. One way is to bring the lumbar back. That's right. The second way? On come back. Mhmm. Yes. But stay down there, not up there. You gotta have to release the sacrum from the the hip bone. Work on the feet. When? Well, within minutes. Yes. But this sacrum is what I want you to do. So that really have a choice? Not so much that. I like that in the back. No. Keep looking. Establishing a midline in the leg from the Yes. From the inside and outside. Yes. It's something else. You did it yesterday? Previous homes. You. What did you do yesterday that really dropped that? Oh, well, you did with gluteus. Right. What I saw when I was doing fourth hour work is is as I established the midline of the inside of the leg, the whole leg began to set back, which allows the pelvis to sit to raise the pubes and drop the coccyx. What connects the coccyx with the pelvis? It's like cord."

From the 1975 Santa Monica class, working through the operational definition of pelvic horizontality:

The Socratic moment where Ida walks the class through the practical mechanics of dropping the coccyx — by bringing the lumbars back, releasing the sacrum, establishing the midline of the leg, working the calcaneus.12

What this passage makes vivid is Ida's habit of refusing to localize the work. The student offering to *work on the coccyx itself* is corrected, not because the coccyx doesn't matter but because the coccyx is downstream of so many other things. To work on the coccyx, in her teaching, is to work on the lumbar that holds it, on the sacrum that articulates with it, on the calcaneus that — through the kinetic chain — communicates with it. The same logic that earlier sent the practitioner to the adductors instead of the floor now sends them to the calcaneus instead of the coccyx.

"And this is the answer, only Steve didn't give you quite the full key. The full key is that this has to do with the floor of the pelvis. And you were talking as though you were dealing with the bony. One is equivalent to the other practically, but nevertheless, I'd like to get this into your imagination. That this fifth hour has to do with the horizontalizing of the floor of the pelvis. Now I haven't heard anything in this class nor do I hear much in any classes come to think of it. To indicate that you people recognize the fact that it is the floor of the pelvis, that is the vital structure in this trip. We talk about pelvis. We are really talking about the floor of the pelvis. And you see in this fourth hour, we went up the legs giving that pelvis enough support that it would be able to horizontalize. When you have mounds of stuff lying along the lame eye or around the hip joint the hip joint in the third hour, the rami in the fourth hour, the rami in the knees, the adductors."

Earlier in the same 1975 Santa Monica class, Ida pressing Steve to name the full key of the fifth hour:

Ida adds the precision Steve missed — the fifth hour is about horizontalizing the floor of the pelvis specifically, not the bony pelvis in general.13

This is one of the few places where Ida states the doctrine in its strongest form: that pelvis-talk in her practice always means floor-talk, even when the language doesn't say so. The fourth hour horizontalizes the floor from below by reaching it through the medial line of the leg. The fifth hour horizontalizes it from in front by reaching it through the rectus abdominis and the psoas. The sixth hour confirms it from behind by working the rotators, the sacrum, and the coccyx. Three different angles of approach, but the same destination.

Why the floor is more than the pubococcygeus

In the 1976 Boulder advanced class, with the senior students gathered, Ida circled back to the question of what actually constitutes the pelvic floor and pushed against the tendency she kept seeing in her practitioners — the tendency to reduce the floor to a single muscle and then fret over how to address it. The passage that follows is one of her most generous and explicit corrections of the reductive frame. The floor is a system, she insisted. The pubococcygeus is the basis of it, but the floor includes the obturator coverings, the spinococcygeal and spinosacral ligaments, the piriformis, the sacrotuberous ligament. The practitioner who attacks the pubococcygeus alone is treating one element of a system as though it were the whole.

"that the pelvic floor is a more complicated thing than simply the pubococci. Right. Well, I mean, that is that is the basis of it. Is the This is true. Now around that, we have other things going on."

From a 1976 Boulder class, Ida resisting the reduction of the floor to a single muscle:

The most direct statement that the pelvic floor is a system, not a muscle — and that students who reduce it to the pubococcygeus are missing the structural picture.14

The corrective is significant because earlier in the same period Ida had been hammering on the pubococcygeus as the key and many practitioners had heard that as a license to make the muscle their target. In the 1976 transcripts she is walking back from that interpretation. The pubococcygeus remains the key — meaning the indicator, the readout, the structural register of how the rest is doing — but it is not the target. The target is the system: obturator, ligaments, rotators, fascia. This is a revision she makes explicitly, not silently, and it shows the way her doctrine continued to firm up across the mid-1970s.

"Oh, to the inductors and how they can get confused. But that's what I've heard from last class, and I was looking for more understanding. Why should you care? Well My question is directed to the idea that you are fretting about one small muscular patch. I'm not saying an unimportant one. But what I what I try to give you people is the understanding of systems. And you're breaking my systems down. This, I feel, is what you people need, an understanding of how systems go together in the body. The medics have been playing with the individual muscles for a long time."

Later in the same 1976 Boulder class, Ida pressing the systems point home:

Ida explicitly names her pedagogical frustration with practitioners who fret over single muscles instead of understanding systems.15

There is real irritation in this exchange — Ida is plainly tired of the question and tired of the framing it represents. But the irritation carries the doctrine. She did not want the floor reduced. She did not want a generation of practitioners producing exquisite work on the pubococcygeus and missing the obturator, the rotators, the lumbar. The floor is the place where many systems meet, and her work was directed at the meeting, not at the patch where the meeting registered.

The fourth hour's adductors, the obturator, the floor

The fourth hour's practical mechanics are worth tracing in detail because they show how Ida's doctrine of indirection actually plays out under the practitioner's hands. The hour begins on the medial line of the leg — the adductors, the inside fascia, the attachments at the ramus and the ischial tuberosity. The practitioner works upward toward the pubes. What is happening, structurally, is that the fascia of the adductors is being released along its continuous extension between the rami into the obturator internus fascia and from there into the floor of the pelvis. The practitioner is reaching the floor by traveling along its fascial neighbors.

"From The this operator internus comes from way in here out to here and the operator fascia which is almost a thickened fascia around the operator internus is actually the attachment of the iliotoxicis muscle. So you're affecting an awful lot of things when you start working these rotators and that's something you have to keep in mind when you're not just working on a muscle, you're working on an awful Go of back to your obturator fascia and say it again. The obturator internus, first of all you don't really have a hole here, you have fascia that covers up this entire foramen. The obturator internus originates all in here, comes out through this greater eschatic notch that attaches to help rotate the femur. But it's covered on the outside by a thickening of fascia called the operator fascia and that's that operator fascia that the iliopoxygus muscle is attached to. So you can actually affect tone of the pelvic floor by just working on that one particular fascial reflex. That fascia extends all the way up from above by the transversal fascia that comes all the way down. Actually join right there. Well, now, do you remember yesterday how much emphasis I put get into."

From the 1973 Big Sur tapes, an anatomical walk through the obturator's role:

The mechanism by which obturator internus work changes the tone of the pelvic floor — the iliococcygeus attaches to the obturator fascia, so working the rotators reorganizes the floor.16

The point is that there is no single approach to the pelvic floor — there are at least three, each anatomically justified. The fourth hour approaches through the adductors and the obturator from below. The fifth hour approaches through the psoas and the rectus abdominis from in front. The sixth hour approaches through the rotators and the obturator internus from behind. Each approach hits a different aspect of the floor's fascial architecture, and each is necessary because no single approach reaches the whole.

"Is the back thing more comfortable and and legging again rather than You can tell by looking out. Yeah. The goal again is the pelvic lift, which having freed up the rami and having freed up the quadratus previously should again begin to Don't forget to free up your hamstrings. Yeah. Deeper hamstrings on a deeper level. But, again, they're attached to the tuberosity of the ischium, which connected the portion of the ring light attachment to the yeah. So all of those structures have to be freed to really begin with it. This is what I want to make so clear in your mind that you can't forget. Yeah. And then, you know, the pelvis looks to organize this plan and the back high we begin to focus on the pelvis but started peripherally this time in the anterior part of the body working predominantly with the rectus abdominis and its attachments. And as far as I know, we started everybody fairly high or at the maneuvering, the fourth, fifth, sixth rib breakfast insertion."

From the RolfA3 tape, walking through the goal of the pelvic lift after fourth-hour work:

Ida insisting that all the fourth-hour work converges on the pelvic lift, which depends on the freed rami and quadratus — and that the deeper hamstrings must also be freed for the pelvis to organize.17

The floor inside the fifth hour

In the fifth hour the approach to the floor reverses direction. Where the fourth hour reached the floor from below through the adductors, the fifth hour reaches it from above through the rectus abdominis and the psoas. Ida described this transition in the RolfB6 public tape, framing the fifth hour as the moment when the pelvic basin begins to turn up in front — providing support for the abdominal viscera and reaching, through the psoas, into the lumbar plexus and through it the diaphragm, the solar plexus, the position of the heart. The floor remains the operative concern; what changes is the direction from which the practitioner reaches it.

"And so in this fifth and fifth hour, you're working your way upward out of the pelvis into the structures whose well-being depends upon the positioning of the pelvis. And you see your fourth hour has taken on the positioning of the floor of the pelvis. And the fifth hour begins to turn it up in the front so that it has support under the abdominal organs. And your sixth hour, you are still working with the pelvis and balancing that basin. You are now going in primarily to balance the sacrum with the rest of the pelvis. Just as through the entire series, we have never gone where we are working. So here, you don't go where you are working, but you go to the areas that influence the sacral position."

From the RolfB6 public tape, on how the fifth hour builds on the fourth:

The cleanest statement that the fourth hour positions the floor from below and the fifth hour turns up the front of the pelvis to support the abdominal organs.18

In the 1975 Boulder class she pushed this further. The fifth hour, Steve Weatherwax suggested, is the second half of the fourth hour — and Ida accepted that framing but added that the key is the floor, not the bony front. The fifth hour horizontalizes the floor by lengthening the front. The two formulations — *floor* and *bony pelvis* — are practically equivalent, she said, but she wanted the floor framing in the students' imaginations because it was the framing the work was actually doing.

"It's literally a continuation. I clearly I clearly saw, you know, last summer that continuation process and how and, you know, Dick talked about how, you know, the only reason it was broken into 10, you know, sessions like that was it because the body just couldn't take all that work. Couldn't take it right. But I just sitting on just trying to figure out how the hell she ever figured out that process, and then began to see it. What she did is what most of of us need to do more. She just sat and watched bodies. And she just kept on doing it."

From the 1975 Boulder advanced class, on the continuous nature of the recipe:

Ida's late-career insistence that the hours are a continuous spectrum, not a sequence of separate events — the floor work begins in hour one and is still being delivered in hour ten.19

The floor inside the sixth hour

By the sixth hour the practitioner is approaching the floor from behind, through the rotators and the sacrum. In the RolfA3 public tape Ida walked the class through how sixth-hour work on the back of the leg is in fact work on the obturators — the real goal of working up the back of the leg, she said, is to get under the rotators. The passage shows how Ida thought about the sixth hour as another floor approach, this time directed at the posterior aspect of the sacrum and the insertions of the rotators that arise inside the pelvis.

"You touched on it and talked about the necessity for getting the rotation of the pelvis around the head of the femur. And I said to myself, he's out of order, but let him alone, but see to it that he shoves this forward. Because what is it that allows the rotation of the pelvis around the head of the femur? The rotator. The rotator. The eminent. So this is our working up. The real goal of working up the back of the leg is to get under the Ruleus. That's right. That's right. And this then is going to be the first hour where we have some hope of getting at the anterior aspect of the sacrum by working externally with the insertion of the rotator which arises in it. That's right. And you see all of this once again is a positioning of the pelvis. Obturator will have the inside of the iliac, the ischial aspect of the iliac. But the whole thing then makes a brand new decision. We also worked on the outside of the sacrum or the posterior aspect of the sacrum. In some cases, freeing up the insertion of hoodies maximus in the fascia and the sacrotoxigeoloidal material true. Material Mhmm. Where where necessary. It is true. Then this hour again, we did a pelvic lift in the back of the neck for balance comfort. And And you observed?"

From the RolfA3 public tape, sixth hour as a third approach to the floor:

The sixth hour reaches the anterior aspect of the sacrum by working externally with the insertions of the rotators that arise from it — a third approach to the same floor.20

What organizes the sixth hour, in Ida's framing, is the same logic that organizes the fourth and the fifth: the floor is reached through its neighbors. The rotators are the neighbors approached in the sixth, just as the adductors were in the fourth and the rectus and psoas were in the fifth. The compound effect of the three approaches is what allows the floor finally to organize as a system rather than as a patch.

"Now has anybody happy to look at the pictures today? If not, why not? Now if the coffee is ready, we can have the coffee, and you can look at the pictures while you're doing the while you're having your coffee and discuss it. And then we'll come back and see what we think is the logical next place. Well, it's a neck organizing hour. I would think that the key probably is the position of the muscles under the jaw. Wouldn't you suppose so? I would have sat down and really thought this thing through because nobody happened to ask that particular question before. The other hour, it seems like I know. Various von Gorman were so added."

From the RolfA3 public tape, looking back across the recipe at the floor as the first milepost:

Ida naming the pelvic floor explicitly as the first milepost the practitioner must register on the road from the fourth hour onward.21

What clean tissue feels like along the iliac crest

Ida insisted that the practitioner's hands, not the textbook, were the final teacher of what tissue around the pelvic floor should feel like when properly organized. In the RolfA2 public tape she described what she meant by *clean* — not a knife-scraped surface, but tissue so freed of its knottiness and strandness that the practitioner's hand could move along it with a free flow. The bony surface — the iliac crest, the costal arch, the ramus — should be clean in this sense before the practitioner can be said to have reached the floor through it.

"You'll hear me over and over again saying, clean off the bony surface. Clean off the bony surface of the costal arch, for instance. I visualize this cleaning off with my fingers as losing the knottyness and losing the strandness where you can move your hand along and have a free flow. And each one of those muscles, as you get to it and you are putting pressure on it, is able to do its own individual giving independent of its neighbor. This is what cleaning off means. Now I bet you go in there with a knife and scrape it. But you go in there with your finger and scrape it, and all of a sudden you have a different quality of tissue. Now those of you who have the senior students here know what I'm talking about when I talk with a different quality of tissue. But those of you who have never seen eighth and ninth and tenth hour work don't know what I'm talking about. This is one of the reasons why no why people can't learn this thing in one's through because they have got to have gone through and seen where they're going to get them and go back and take another look at how they get there. Otherwise, you're handling the situation blind. Now does this present a different emphasis for that third hour?

From the RolfA2 public tape, on what 'clean' tissue means to the practitioner's hand:

Ida's tactile teaching on what reaching the floor through the iliac crest actually feels like — the loss of knottiness and strandness, each muscle giving independently of its neighbor.22

The tactile language matters because Ida's doctrine cannot be applied from a diagram. The fascial continuities Tom Wing traced in his anatomy lecture must be felt as continuities under the hand for the floor work to land. Ida's repeated insistence that you must see senior practitioners' eighth, ninth, and tenth-hour work before you understand the earlier hours reflects her view that the standard for what *clean* means cannot be transmitted in words. It must be transmitted in apprenticeship.

What the practitioner does not do directly

It is worth saying plainly what Ida's pelvic-floor doctrine forbids as well as what it requires. The practitioner does not, in her teaching, attack the pubococcygeus directly. The work is not internal. The floor is reached through its supports — the adductors, the obturator, the rotators, the lumbar, the coccyx — not through penetration of the pelvic cavity. In a 1975 Boulder dialogue captured on the T9SB tape, a student described the fourth-hour goal as freeing the pelvis from below, and Ida corrected the framing: the work is not only freeing the pelvis from below, it is putting *organized support* under the pelvis so that the pelvis can be free.

"vision I have is that Realize that it isn't only freeing the pelvis from below. It's putting support under the pelvis so that the pelvis can be free. Okay. This is so little. Would you say organized support? Yes. Hello? Yeah. Okay. Yeah. And so you wanna you wanna free all the attachments to the ramus into the ischial tuberosity and lengthen the hamstrings some more. Once again, lengthen the lumbar and balance that workout by lengthening the cervicals and just more work on the back. Now I think we're ready to go to the power. Sir, finish up each session, each of your descriptions of the session with this very brief."

From the 1975 Boulder advanced class, on the difference between freeing the pelvis and supporting it:

Ida's distinction between *freeing from below* and *putting organized support under* — the floor work is not subtractive but compositional.23

*Organized support* is the phrase that does the work in this exchange. The floor cannot simply be released; the structures beneath it must be organized into a coherent supporting architecture. A freed pelvis with disorganized support beneath it is no better than a bound pelvis. The medial line of the leg — the adductors, the inner fascia, the calcaneus seated straight — provides the support; the work on the rami and the ischial tuberosity provides the freedom. The floor reorganizes when both are delivered.

The floor as readout of the whole

By the time Ida was teaching her late-career classes she had arrived at a position that gathered all of the preceding doctrines into a single claim: the pelvic floor is the body's structural readout. Look at the floor and you can tell what the legs are doing, what the lumbar is doing, what the coccyx is doing, what the rotators are doing. The floor is where the whole body's organization registers. This is why she resisted reducing it to a muscle, why she pressed students to think systemically, why she made the coccyx a diagnostic indicator, and why she defined horizontality at the pubic-coccygeal line. The floor is the place the body tells the practitioner the truth.

"Speaking of the iliopsoas muscle, when I was taking my audition class, I think the brains are in the pubococcius muscle and when in doubt say psoas. But Well, I really I really mean what I say. You get to know so damn much about that iliopsoas that you don't know anything about a body. Yeah. Although he talks about reducing spinal curvatures by balancing the psoas. Well, all right. A great many chiropractors have done the same thing, and there's a whole school of chiropractic, for instance, that sells the idea that you can straighten the spine as well as the spinal cord."

From the IPRVital tape, Ida warning against over-attachment to single-muscle frames:

Ida's late-career warning that becoming an expert on a single muscle — even the iliopsoas — costs the practitioner the body itself.24

There is a real tension in Ida's teaching here. She named the pubococcygeus as the key of the floor in the early 1970s and then spent the rest of her teaching career making sure her students didn't take her at her word. The key, in her usage, was always the index — the place where you read the body's organization — not the place where you operated. The practitioner who heard *key* as *target* had heard her wrong, and her impatience with this misreading grew across the years.

"Know that each horizontal that you bring out down below reflects itself upward as we saw in Takashi yesterday where he's working on his leg and you can see his rib cage absorbing the change. I mean this, when the tissue is in tension, that's stored energy that you release into the body. And its energy is not a metaphysical something. These molecules are aligned in a particular way. You change their alignment. The change spreads."

From the 1975 Boulder advanced class, on how changes propagate through tensioned tissue:

Ida's mechanism for why floor work can be reached from so many directions — tissue under tension stores energy whose release propagates structurally.25

Coda: the floor as the body's bottom

Across all the passages where Ida returned to the pelvic floor, one phrase recurs that captures her doctrine most economically: *you've got to stand it on its bottom.* The body is built upward from the floor. The first hour begins the floor work by suspending the thorax above the pelvis; the second deepens it; the third reaches the quadratus that holds the rib cage off the pelvis; the fourth approaches the floor from below; the fifth from in front; the sixth from behind. By the seventh hour the floor's organization has propagated upward into the neck, and by the tenth it is delivering the verticality the work has been aiming at all along.

"But all of this is a very important consideration for you that to get in there, you have to get to the ligaments that relate the coccyx, the sacrum, and the STI. Now this is a little bit of a terrifying business to you junior people. That's a terrible long way to be into a person. And it's a scary way. And they're scared. And you're scared. And everybody's scared. It's the only way you'll ever get that body organized. This is the bottom. You've got to stand it on its bottom."

Closing thought from the 1971-72 mystery tapes:

Ida's most compact statement that the practitioner must reach the bottom of the body — and that this is the only way to organize the whole.26

The pelvic floor is, in this sense, the foundation of the entire structural-integration project. Not because it is the most important muscle, or the most often worked, or the most carefully named — but because it is the architectural plane on which everything above it depends. The practitioner who has not organized the floor has not organized the body, and the floor cannot be organized except by organizing what holds it. This was Ida's doctrine in the early 1970s; this was her doctrine in 1976; and the firmness with which she defended it against simpler interpretations is one of the clearest signs of how central she considered it to the whole of the work.

Each source row expands to show how the chapter relates to the topic.

1 Pubococcygeus and Kegel's Discovery various · RolfB3 — Public Tapeat 53:14

Ida walks the class through the logic of the fourth hour: the pelvis must be horizontalized not for gravity's sake alone but to support the viscera; that support depends on the integrity of the floor; and the floor's defining structure is the pubococcygeus. A student names it and Ida confirms the answer while signaling that the muscle is the key, not the whole — the autonomic ganglia and other structures will come into the discussion in due course. The passage is foundational because it shows her insisting that the class arrive at the muscle through reasoning, not memorization.

2 Pubococcygeus and Kegel's Discovery various · RolfB3 — Public Tapeat 54:32

Ida insists that nothing in the body rests anywhere — everything must be suspended somewhere. She frames this as the cardinal difference between her thinking and what she calls the well-meaning but mistaken view of the medical mainstream, which assumes that gravity pulls everything down and that organs therefore rest on whatever structure is beneath them. For Ida, organized force fields make resting unnecessary; the organs swim rather than sit. The passage explains why she objects so strongly when a student describes the viscera as resting on the pelvic floor.

3 Pubococcygeus and Kegel's Discovery various · RolfB3 — Public Tapeat 56:04

Ida describes the consequence of a balanced pubococcygeus: a balancing of physiological forces within the body that allows the suspension of viscera to actually occur, rather than collapse into resting. The passage moves from the negative pole — what happens when the floor fails — to the positive: what becomes possible when it holds. It sets up her brief history of how Kegel discovered the muscle and what changed in medical thinking once it was recognized.

4 Return to Pelvic Floor Determinants various · RolfB4 — Public Tapeat 58:38

Ida insists that what determines the position of the pelvic floor is not the half-dozen muscles students have memorized as composing it, but the sacroiliac articulation, the joint between the fifth lumbar and the sacrum, and the joint between the fourth and fifth lumbars. The passage names the bony articulations as primary and the muscular sling as consequential. It is the teaching that organizes her entire fourth-hour pedagogy: you reach the floor by reorganizing the joints that hold it, not by attacking the muscles that compose it.

5 Return to Pelvic Floor Determinants various · RolfB4 — Public Tapeat 59:12

Ida lists the everyday postures that alter pelvic-floor position without touching the floor itself: shortened hamstrings from one-sided athletic training, knee-spreading postures that shorten the adductors and the brassless and alter the hamstring relationship. Each habit is named as a way of disorganizing the floor through structures that compose its frame rather than through the floor's own muscles. The passage gives the practitioner a diagnostic vocabulary for reading the floor from the legs and the lumbar.

6 Third Hour Prepares Fourth Hour various · RolfA2 — Public Tapeat 6:13

Ida corrects a student who has named the pelvic floor as a goal of the fourth hour alongside the medial line. She insists there is no *and* — establish the medial line and you have established the floor. The floor is not a separate goal but the end point of a road. The passage encodes one of her most consistent pedagogical claims: that the structures we cannot work on directly are reached by working on the structures that compose them. The principle organizes her entire approach to the fourth hour and explains why her practitioners spend most of the session on the adductors and the rami rather than on the floor itself.

7 Fourth Hour: Adductors and Pelvic Floor 1971-72 · Mystery Tapes — CD1at 12:51

A senior student names the fascial pathway by which fourth-hour adductor work travels into the pelvic floor: the fascia wrapping the adductors and the inside of the leg extends up between the rami, blends with the obturator internus fascia, and becomes part of the floor of the pelvis. By releasing the legs, one changes the tone of the floor. Ida accepts the answer as substantially correct and adds that the same fascia in turn blends with the iliac fascia further up — establishing the continuous fascial column that justifies her pedagogy of reaching the floor through the leg.

8 Iliac Fascia and Pelvic Bowl Continuities 1974 · IPR Lecture — Aug 11, 1974at 1:58

Wing describes the pelvis as two bowls — an upper bowl formed by the iliac wing and a deeper inner bowl whose floor is the pelvic diaphragm. He traces the iliac fascia's continuities: with the transversalis fascia of the abdomen, with the quadratus lumborum fascia, with the piriformis fascia from the sacrum, with the obturator internus fascia, and with the fascia lata through the iliopsoas tendon. The passage gives anatomical specificity to Ida's pedagogical claim that work anywhere along this continuous fascial system reaches the floor.

9 The Pelvic Diaphragm and Its Fascia 1974 · IPR Lecture — Aug 11, 1974at 22:31

Wing names the muscles that compose the pelvic diaphragm — pubococcygeus, ischiococcygeus, coccygeus — and traces their attachments from the inner rim of the pubic bones across the obturator fascia back to the coccyx. He describes how the obturator fascia divides, with the superior portion continuous with the superior fascia of the pelvic diaphragm. The passage is the formal anatomical companion to Ida's structural insistence that the floor is reached through the legs and lumbar.

10 The Coccyx and Ganglion of Impar various · RolfB6 — Public Tapeat 49:08

Ida argues that the coccyx, conventionally dismissed in medical thinking as an unimportant residual structure, is in fact a very significant indicator of what is going on structurally. She names two reasons: it gears into the nervous system through the placement of the autonomic ganglia, and it is the anchorage for the pubococcygeus. Without an appropriately organized coccyx, the floor cannot be appropriately toned. The passage justifies her insistence on attending to the coccyx in the sixth hour as well as the fourth.

11 Coccyx, Sacrum and Horizontalizing Pelvis 1971-72 · Mystery Tapes — CD1at 15:44

Ida tells the class that without organizing the ligaments connecting the coccyx, sacrum, and ischial tuberosity, there is no way to horizontalize the pelvic floor. She acknowledges the practical fear involved — both the practitioner and the client are frightened by the depth required — but insists it is the only way to organize the body from its base. The passage makes plain that the pelvic-floor work is not a delicate procedure performed lightly but a structural intervention reaching into the deep ligamentous architecture of the pelvis.

12 Opening and Class Logistics 1975 · Rolf Advanced Class 1975 — Boulderat 1:08

Ida presses the class to define pelvic horizontality as the line from the second segment of the coccyx to the pubes approaching horizontal. She then walks them through the practical means of achieving that line: bringing the lumbar vertebrae back, releasing the sacrum from the iliac bone, establishing the midline of the leg from inside and outside, working the calcaneus. Each maneuver drops the coccyx by changing the architecture that holds it. The dialogue with Steve and the other students shows the cause-and-effect chain Ida wanted them to internalize.

13 Defining the Fifth Hour 1975 · Rolf Advanced Class 1975 — Boulderat 4:32

Steve Weatherwax has just delivered a careful answer about the fifth hour — the front needing to lengthen, the pelvis needing to come up anteriorly, integration between upper and lower halves. Ida compliments him and supplies the full key: this fifth-hour work is about the floor of the pelvis specifically. She complains that students in her classes consistently fail to recognize the floor as the vital structure of the work. When we talk about pelvis, she says, we are really talking about the floor of the pelvis.

14 Seventh Hour and Pelvic Floor Anatomy various · RolfA3 — Public Tapeat 54:32

Ida tells the class she wants every practitioner conscious that the pelvic floor is a more complicated thing than simply the pubococcygeus. The pubococcygeus is the basis of it — she accepts that — but around it she lists the obturator covering, the spinococcygeal and spinosacral ligaments, the equivalent muscle structures, the sacrotuberous ligament, the piriformis. The passage is the corrective to her own earlier emphasis: the floor is a system, and the systems-level view is what she wants her practitioners to carry.

15 Systems vs Individual Muscles 1976 · Rolf Advanced Class 1976at 21:04

A student named Peter asks for more on the pubococcygeal muscle and Ida pushes back. She is not, she says, interested in teaching them to fret about one small muscular patch — not because the patch is unimportant but because what she is trying to give them is the understanding of systems, and the question is breaking her systems down. The passage encodes her late-career pedagogy: she wanted her practitioners to think in fascial continuities and force balances, not in muscle-by-muscle targets.

16 Obturator Internus and Pelvic Floor 1973 · Big Sur 1973 — Tape 12at 23:59

A senior practitioner walks Ida through the anatomy: the obturator internus originates on the inner surface of the obturator foramen and emerges through the greater sciatic notch to rotate the femur, while its external fascia — a thickening called the obturator fascia — is the attachment of the iliococcygeus muscle. By working on the rotators, the practitioner can affect the tone of the pelvic floor through this single fascial reflex. The passage names the mechanism by which sixth-hour rotator work reaches the floor.

17 Client Emotional Reactions to Work various · RolfA3 — Public Tapeat 1:34

Ida walks the class through the structural targets of the fourth-hour pelvic lift: the rami and the quadratus must be freed first, and the deeper hamstrings — attached to the tuberosity of the ischium and to the ring of attachments around the pelvis — must also be freed so that the pelvic lift can deliver its result. The passage shows how every structure she names is reached so that the pelvic lift can land. The work is convergent: a dozen approaches all aimed at the moment when the floor reorganizes.

18 Review of Hours One Through Six various · RolfB6 — Public Tapeat 10:25

Ida explains how the fifth hour builds on the fourth: the fourth hour has organized the floor of the pelvis from below; the fifth hour begins to turn the pelvis up in the front so that it has support under the abdominal organs. The passage describes the structural choreography of how the floor work extends upward — through the rectus, through the psoas, eventually reaching the diaphragm and the heart's position. It is one of the clearest pictures of how floor work is not a single-hour event but a series of approaches across the recipe.

19 Three Primary Manifestations of Disease 1975 · Rolf Advanced Class 1975 — Boulderat 0:36

Ida emphasizes that the first hour is the beginning of the tenth, that the second hour is a follow-up of the first, that the third is the second half of the second and first — that the recipe is literally a continuation, broken into ten only because the body cannot take all the work at once. A senior practitioner notes that Ida has been putting more and more emphasis on the lumbars and the lumbodorsal hinge because students tend to forget those structures when they hear only *pelvis*. The passage situates floor work as an ongoing teleology across the entire recipe.

20 Sixth Hour: Posterior and Rotators various · RolfA3 — Public Tapeat 47:17

Ida walks the class through the sixth hour's structural target: getting under the rotators by working up the back of the leg, then approaching the anterior aspect of the sacrum through the insertions of the rotators which arise in it. She names this as the first hour where the practitioner has hope of reaching the anterior sacrum from outside. The work then continues onto the posterior aspect of the sacrum, the gluteus maximus insertions, and the sacrotuberous and sacrospinous ligaments. Each of these structures is named as a way of reorganizing the pelvis.

21 Sixth Hour: Posterior and Rotators various · RolfA3 — Public Tapeat 51:42

Ida proposes going back to the fourth hour and walking forward through the signposts of the recipe, naming the pelvic floor as the first milepost. She asks a senior practitioner to literally name the structures that compose the floor, and works through the pubococcygeus's line of insertion — from the spinous process across the ischium to the back of the pubes. The passage is one of the few places where she organizes the recipe explicitly around the floor as the first major checkpoint and uses that checkpoint to organize the practitioner's sense of progression.

22 Third Hour and Quadratus Lumborum various · RolfA2 — Public Tapeat 3:55

Ida explains what she means by cleaning off a bony surface like the iliac crest. The flesh must be so organized that it can stretch as it is demanded to — losing knottiness, losing strandness, each muscle giving independently of its neighbor when pressure is put on it. She names this as what distinguishes eighth, ninth, and tenth-hour work that junior practitioners cannot yet recognize. The passage is the tactile companion to her structural doctrine: the floor is reached through tissue that becomes responsive in a particular way, and the hand learns to read that responsiveness.

23 Quadratus, Twelfth Rib and Psoas 1975 · Rolf Advanced Class 1975 — Boulderat 0:00

A senior practitioner describes the fourth-hour work as freeing the pelvis from below. Ida reframes: it isn't only freeing the pelvis from below, it is putting organized support under the pelvis so that the pelvis can be free. She accepts the corrected language — *organized support* — and the dialogue continues with attention to the ramus, the ischial tuberosity, the lengthening of the hamstrings. The passage encodes her doctrine that pelvic-floor work is constructive, not just releasing.

24 Focusing Body and Gravitational Field 1971-72 · Mystery Tapes — CD2at 2:32

A senior practitioner reports that a colleague has written a book on the iliopsoas and Ida warns the class away from it. You can get to know so much about the iliopsoas, she says, that you don't know anything about a body. The passage is the broader principle that organizes her pelvic-floor teaching: any structure named as the key — pubococcygeus, iliopsoas, psoas — becomes a trap if it pulls the practitioner's attention away from the systemic relationships the structure is registering.

25 Three Primary Manifestations of Disease 1975 · Rolf Advanced Class 1975 — Boulderat 1:15

Ida is in dialogue with students about how the body integrates changes between hours. Michael Salison's image of a fascial tube starting in the cervicals enters the conversation; Ida adds her own gloss — when the tissue is in tension, that's stored energy that releases into the body when it is freed. The molecules align in a particular way; you change their alignment; the change spreads. The passage names the mechanism by which the floor work, delivered from the adductors or the rotators or the rectus, propagates through the tissue to reach the floor itself.

26 Coccyx, Sacrum and Horizontalizing Pelvis 1971-72 · Mystery Tapes — CD1at 16:50

Ida acknowledges that going as deep as the coccyx, sacrum, and ischial tuberosity ligaments is a terrifying business for junior practitioners — a long way to be into a person, scary for both practitioner and client. She refuses to soften the requirement. It's the only way you'll ever get that body organized, she says. This is the bottom. You've got to stand it on its bottom. The passage encodes the doctrinal commitment that organizes her whole approach to the pelvic floor: the body's verticality is built up from a floor that has itself been organized, and there is no shortcut around that requirement.
