Because the deeper orientation requires that the sacrum move and the lumbar spine moves. Good morning. Happy Monday. I have no coffee in hand and it is perfect. All right. Strong Monday, coming off of a cool day yesterday. So yesterday was Mother's Day. My mom is 88. We had the entire family together for the first time, I think in over a year. So that was kind of cool and good for her. So I hope you had the opportunity to appreciate your mom. Little housekeeping, iFastU Q&A from last week is posted for those of you who are iFast University members. If you're not a member, please go to ifastuniversity.com and get yourself signed up for that. Let's dig right into today's Q&A. Today's Q&A's with Jordan. Jordan is a regular on the Thursday morning, 6 a.m. Thursday morning, coffee and coaches conference calls. He's also a physical therapy student. And so he had a really good question in regards to some of the narrow ISA foundational archetype representations. So gaining some clarity with that, we also kind of led into how we may influence some of the early and late representations of external rotation. And we made reference to actually one of the squat activities that we used to sort of recapture that. So again, adding clarity to the archetype and then how we're going to move into those early and late representations. So very cool. If you still have questions about those concepts, this is going to be a great call for you if you would like to participate in a 15 minute Q&A with yours truly, please go to askbillhartman at gmail.com, askbillhartman at gmail.com, put 15 minute consultation in the subject line so I don't delete it, and we will arrange that at our mutual convenience. Everybody have an outstanding Monday, and I'll see you tomorrow.

We are recording. Timer has started. Jordan, what is your question?

So I've been getting so caught up in wide ISAs just because I've worked with athletes. It just so happens we've been talking a lot about wide ISA people, so I've been focusing on that. I was going back through some old stuff and switching my focus to narrow ISAs with Zach talking about his ACL patients. I just wanted to run this by you. My first question is: for your narrow ISAs, the initial presentation is going to be a lower posterior pelvic compartment compressed, correct?

Okay, so let's clarify this because I think there is some confusion in this regard. So we have to look at the shape, all right? So when we look at an inhaled representation of the pelvis, that's what we're talking about. So we're talking about a counter-neutated representation, but let's not confuse this with someone that has a superficial compressive strategy in the posterior lower aspect of the pelvis because that's not the same thing. So the diaphragm shape as you breathe in has expansion in the anterior aspect of the outlet, okay? So the relative position posteriorly is not expanded. So rather than saying compressed, it is, but let's just say that it's not expanded under those circumstances because we want to differentiate between a posterior lower compressive strategy, which is superficial, relative to this, and we could call it a normal inhaled representation of the pelvis first and foremost. So that's where we're starting from when we're talking about the foundational representation of the narrow ISA archetype. Does that make sense?

Yeah.

Okay, so as long as you're clear on that because essentially what it is, it's the position just doesn't allow that area to expand as you breathe in. So we get an anterior expansion on that inhalation or actually in the exhaled compensatory strategy that starts this whole process of the narrow ISAs behaviors from that point forward is that anterior aspect is where that expansion persists. So even on the exhale, they still have the anterior expansion.

Okay. That, okay. And so then the domino effect of what will happen with their ADL and their training will typically follow that superficial musculature pattern.

Absolutely. But understand that the sequence of events is a little bit different because with your wide ISAs, their first response to the compensatory strategy in regards to breathing is that they're going to get pushed backwards. So their response is to push back forward. Whereas with your narrow ISAs, because they trap air anteriorly, the expansion is forward. So they fall forward first. So their first superficial compensatory strategy is going to be to push back. So that's the differentiator between the two. And then, of course, then you've got this sort of ping pong effect of anterior to posterior compressive strategies to maintain center of gravity. And then whatever resulted wherever they are in space under those circumstances, that determines what we end up measuring or observing during movement.

That makes sense because you lose that interrotation initially. I guess, relatively first.

So when they compress anteriorly, yes, you're going to start to lose the internal rotation because they still have posterior expansion under those circumstances. In fact, I'm kind of forcing it under those circumstances where I'm pushing from the front, I have expansion posteriorly. That maintains my ER representation, but I'm losing IR under those circumstances.

And then this is a perfect leading way. So then what will follow that is, once they're pushed back, they'll do some sort of ping-pong to counter that. So that's when you'll start to see that dumping, that anterior orientation.

Right. So think about the initial counter-neutated representation. So I should have that expansion at the base of the sacrum, which would bring the lumbar spine with it if we're just talking about the pelvis, or I would have that expansion where I would see dorsal rostral expansion under those circumstances. But then as the superficial strategies are applied, and I start to see that changed orientation, that's where I'm gonna start to see the anti-orientation show up in a narrow. Because they get it too. Again, it's just that the sequence is a little bit different.

I think that was what was tripping me up. Now, I think what was really confusing me, I guess it'll be different in terms of when you sequence certain exercises, but I saw some of you did like with a band around the knees, like your classic like right through the excursion, but you've also done a squat or like a hook lying with the ball in between the knees. I get the hook lying one where you're opening the posterior lower, the band around the knees though through the squat. I'm a little bit confused. Can you clarify that?

So you have to think about where we are in space because they're not in the same place. When I'm in hook lying and you look at the amount of hip bending, it's totally different from the squat. So what we're doing with the band in the deep squat is: as I gain depth and if I have the anti-orientation, all that musculature above the trochanter is going to be biased towards internal rotation. If I'm trying to improve the descent to increase the depth of my squat to capture that early representation, I have to eliminate the influence of that internal rotation. Otherwise, I won't capture the depth that I want, and I won't get the diaphragm position that I want. By fixing the femurs—so I'm not pushing out against the resistance; I'm holding my position against the resistance—what that does is it's an external rotation force. That means as I descend and that anti-orientation becomes an internal rotation influence, if I'm resisting, I reduce the internal rotation influence. So the musculature is less likely to produce internal rotation at that point, which allows me to eccentrically orient and descend. I'm going to capture the representation where the musculature that's pushing me forward, compressing the base of the sacrum, will release its concentric orientation, because I've got the external rotation force. That's going to allow the sacrum to tilt backward in the depth of the squat so it can actually capture the early representation of the deep squat.

So basically you're not necessarily creating space, you're maintaining space for that internal rotation to kind of

If I am compressing the base of the sacrum forward as I descend into the deepest part of a squat, there is no way for me to descend that diaphragm to allow that to occur. Okay. Because of the anti-orientation. It's just can't happen. So I have to have, I have to, I have to reduce the concentric orientation of the, of that IR, IR ring musculature.

Okay.

So the band creates an ER demand to be maintained throughout. So it allows the sacrum to counter-nutate at the bottom of the deep spot.

That makes, yeah, I get it now.

It's sneaky because traditionally what people have done is they say you need to push out and push more. Yeah, I get that. But if I actively ER at the hip, I'm going to push outward to create that ER space, but that's going to push the pelvis forward, and that becomes a late propulsive strategy. If I get late at the top of the squat, I want early at the bottom of the squat. I can't push out because that's propelling me forward. I need to create a delay strategy at the bottom. So I have to have expansion at the base of the sacrum. I have to be able to yield under those circumstances. If I can't do that, then I don't descend into the squat in an early representation because that's my goal with the band.

Yeah. Thank you. Exactly. And then my next question in relation to this, when I think of deep squat, my initial thought was heels elevated, right? But I know you've talked about for those narrows, like you got to be careful because I guess you mentioned like hiding the $100 bill. Can you go over that? Cause I feel like with the band, if you combine that, wouldn't that help with the heels elevated or is it going to be counterintuitive?

Okay, so let's be very clear on what the goal is. So is the goal to acquire best depth, which would be the early representation of the pelvis and the deep squat? Is that correct?

Yeah.

Okay. So let's start with the foot representation first. So we're very clear on what we mean by a heels elevated representation. So what I want to have is I want to have the foot on the platform. All right. So it's one platform because if I just have the heel elevated and I have the toes extended, I put myself in a late representation, which means that I won't get the yielding action that I want in the bottom of the squat.

I was thinking for when you were talking about using a band around the knees to help people get deeper, but then you've also talked about combining those two exercises. However, I think you explained in the past that you get that like hiding the hundred dollar bill example.

You have to be careful with this. Because what some folks will do when you're cueing pelvic position as they're descending into the squat is that because they're at the top, that is a late representation in regard to pelvic orientation. So the foot's going to bias us towards the early, but I can still create that posterior lower compressive strategy as they're posteriorly orienting. So if I have something that's anteriorly oriented and you're cueing posterior orientation, you have to be very careful that they're not closing that posterior outlet actively, which pushes them forward into that late representation. Because if they hang onto that at the bottom of the squat, there's no way they're going to be able to sit down. And that might require you to do the hook lying activity first, where I have to be able to cue them out of that posterior lower concentric orientation. The way you'll know you've alleviated that is you'll recapture early range hip flexion, recapture straight leg raise, and pick up some internal rotation at that traditional 90 degrees where we test our ER and IR at 90 degrees of traditional hip flexion. So if you pick up and you won't necessarily get full internal rotation, we're looking for an early representation which will not have full internal rotation, but you will have a measure of it. For instance, if we were looking at 40 degrees of traditional IR being considered the average, you might have 20, and then you know you've got enough to capture that early representation. You follow?

Yeah.

Okay, cool. So your understanding of the strategy for that early representation and hook lying I think is on point. I think the clarity then is just when you're trying to capture that deeper orientation. Because the deeper orientation requires that the sacrum move and the lumbar spine moves. When you have the earlier representation, where I have ilium forward and still a sacral counter-nutation, that's that late representation where I'm pushing the base of the sacrum forward. Okay? That's not the same, that's not the same as capturing that deep orientation, okay? One's late, up at the top, at the squat and early, down at the bottom.

You see it? Yeah, that clarifies it a lot. Thank you.

Awesome. Any other questions?
