A real quick follow-up. When you see somebody who walks and they have hyper-extensor thrust, is that hyper-extensor thrust? That's when they're going through mid-stance and the knee snaps back really quickly. So what is that? Is that them pretty much skipping mid-stance and going straight to late stance?

So you're providing them with a sensation. So you're doing exactly what we just talked about. It's like providing them with a sensation. So you're doing exactly what we just talked about.

It's not guaranteed. In fact, most people fail miserably.

Yes.

Can't see your feet, boss.

So you need a stick and a fulcrum, right?

Bill, on the points of contact thing: when you say you're doing a backwards over the left shoulder roll and the points of contact are starting to diminish, the points of contact say you're on your left scapula and your left occiput. That's where the delay is occurring for that roll, and that's where you can get the expansion back on those points of contact. That's the primary focus.

Okay, yeah. That's a delay. It's not a turn. You understand that, right?

Perfect. How does relative motion change happen? For example, how does getting air into the anterior thorax increase internal rotation? What changes have to happen in the tissue? Maybe you can explain in the muscles for it to be easier to understand. Or maybe what shape change has to happen in the thorax.

There you go. That's what we're talking about. If you're laying on your side in a low oblique sit, and if you can get on the inferior aspect of that trochanter, which would be the backside when you were standing up, you're going to push that femur into IR relative to the pelvis. So you're going to drive IR from the ground up into the pelvis. That would be a favorable representation of the pelvis if you're trying to capture internal rotation on that hip.

So in this case, when we were talking about the gate, the middle representation is just like one on top of the other.

Just, okay. Yeah. You probably just had them back a little bit too far. Yeah. They were leaning backwards too much and they were not leaning into the sit. You need to get a little bit more pressure from ischium to hand.

Yeah.

You can see the differential. Sometimes it's really close, and so those would be people who would have a different strategy. Some people are the other way, like some people look like a V.

All right. Cool. And knowing that connective tissue tuning is kind of like the immediate conditioning that you do, conditioning not in the cardiovascular sense, but in the Pavlovian sense, where you kind of give me that reaction thing. And then over time, on a more broad level, you just train them into physically becoming adapted to what you asked of them through repetition.

What happens approximately when you do that?

Right. So you're going to end up. Think about this. You've constrained relative motions. So you're behaving in a space with some measure of relative motion, but as you get to the ends of the activity, it's all gone, right? So you're gonna be in like anything that you do beyond that point. So as your right big toe is on the ground, right? That becomes the last element of superimposition of IR and ER, right? But there's not a whole lot of relative motion there.

If I'm creating a delay on the left, can I challenge their ability to maintain it? Yes.

Oh, the elbow. K, heel. Say it, Ian.

Mm hmm.

Yeah.

So to move through space, you have to have an ER strategy, which is expansion. If I exceed your maximum effort in an exercise, the reason that you can't move is because you can't expand under that load. That's what being strong enough means, right? Is that I can expand, I can move through space, and then I can compress myself back into the shape that gets me back up into the start position.

I suppose you could hook a kettlebell on your foot and hold your leg up.

Yeah. What would you do? Actually, I don't even think that would be too fun. Nothing to learn.

Do you think it's the solution?

Right, right.

Which change are you making reference to my friend?

Okay.

Yeah.

No.
