The wide ISA is going to get pushed from behind first. So narrow ISA gets pushed backward. The sternum gets compressed first. The dorsal rostrum gets compressed first on the wide. So again, the sequencing of events is a little bit different, but their end positions will be the same because they have all of the compressor strategies layered on.

I think you can speak. I think you can just take the step back and take the, I guess it would be for you a 10 meter view. So you're going to stand way back and you're going to look at them. What would be the interference? So I'm trying to get to a position where movement's going to stop. So this becomes the superposition of ERs and IRs. This is forced as aggressively into the ground that I can produce right before the max P, where I'm going to release some energy. So I got to get the downforce in this scenario. What interferes with that capacity?

OK. And then so follow up to that. When I look at their ISA on the table, can they open? Can they close? It appears that the right side looks closed. Like that right, the angle on the right ISA is more vertical. The lower so doing it this way, they look more closed on the right side.

So there's a twist at the top where motion stops, where the relative motion of the body stops, but the body continues to twist. Yes, got it. That is a compression. That is a middle, middle propulsive representation. Because in middle, everything gets compressed and movement stops.

Okay, so just a clarifying point that I picked up on there for me. I just want to make sure I've got this. Initially, I was under the impression that maybe he didn't have a posterior lower left compression at the bottom there because I thought that he was moving back to the left on the deadlift hinge and had that area of being compressed. Then that would have seen him move to the right rather than move to the left. But it's just occurred to me fairly recently that I think that if he has a posterior lower left compression there as well, then he simply, as Ian pointed out, his starting condition would mean that he's already turned to the left and then as he moves back, he moves back as one unit just in that direction. That's basically the difference. Whereas if he didn't have that compression, then we would see him present relatively square at the hip and then when he moved back, he would move into that position as opposed to just moving back as one full piece. Is that the defining point between those two?

So I guess my thing is that there are these multiple strategies, and I'm trying to sort them out in my mind as to whether it's just a matter of experimentation or if it's a matter of principle. So I'm trying to reconcile those three.

Which way would you be turning? So if you're reaching forward, all you have to do is reach forward now. It's like reaching forward with your arm. It's like, what are you, which way are you turning the axial skeleton? That's basically what you want to look at.

Okay. So if he's pushing into the ground like that, that's the problem. Because you're creating a space in the medial knee. Push through your knee like this. You compress it, and he goes, 'Oh, I feel it right there.' He pushes and feels it right there because that's where it's expanding where it should not expand. So what I have to do, from this position, is teach him to put force into the ground there. Now the forces are going straight down through the knee versus through that twist. Does that make sense?

Bill:
SPEAKER_05 32:02–32:48
Yep, exactly right. It's like, I can't hold an ER, I can't maintain the IR as I'm turning him. So what do I do? I just magnify more ER. So the IR compensation is the anti-orientation. The ER compensatory strategies is ER at the hip, all the way down to the foot. So if I see the knees separate as he's trying to shift from, if I'm trying to turn him from right to left, I know he's starting to ER. If he picks up his foot, that's a pretty big ER. If the anterior orients, then I know that he doesn't have the capacity to maintain the ER as he's sliding back. You see it? Don't have to retest the tests at all. You just look for the compensatory stretch.

Except in the golf swing, they say, oh, it's your backswing. So if I'm a right-handed golfer in a backswing, I use early propulsion on the right side and late propulsion on the left side to get the club into the top of the backswing.

I'm literally right here inside this box and I control everything. So my inputs equal my outputs. When there is an imbalance between the reinforcing and the balancing loops, my reinforcing loops become predominant. That's going to be a reduction of adaptability of the system, but it could be favorable for certain things and unfavorable for other things.

There you go. Yeah. So you give her an early ER representation, right? So it's a short stagger. So we don't want to get too far away from middle P because we want downward force. But I stagger her a little bit here, right? She's catching the ball straight through the middle. And now I have the ER representation that you wanted, right? It's just like your right suitcase carry. Right? It's just like Taya's right foot forward split squat. You see? Got it. Got it. Got it. Yeah. So again, you're, so the exercises start to point, like the exercises teach you the best place to put things as long as you understand what your intention is. They call it neuro and ortho.

Yeah, it's going to be your femur is going to be the next one. And then for me to get that down, I've got a downward force that's going to fall inside the foot. Otherwise, like I said, if the force is on the outside edge of the foot, that foot is going to slide down the surface. So I have to create the downward force inside the base of support, which is going to be the next available is going to be the femur.
