So I'm thinking like cross connects. No, I don't think you have space for that yet. You've been in a client.

So there used to be like a heavy club that they used to sell back when I used to work with golfers that weighed two pounds. Okay. So that doesn't sound like a lot of weight, but if your driver is 15 ounces, less than a pound, okay? And you double the weight, you've just changed the activity. Like it's no longer the same swing that you had at the lighter weight. You can disturb the load plus or minus about 20% without changing the motor activity to a significant degree. So let me give you another example. Baseball players, they throw weighted balls or lighter balls. So official baseball is five ounces. And so if you add 20% to that, that's a six ounce ball, okay? That's pretty useful because it doesn't disturb the normal behavior of throwing too much. I could throw a four ounce ball, that doesn't disturb it too much. But if I threw one that was say seven ounces, now that's a 40% increase. And now I've actually disturbed the output and it changes it significantly.

Yes.

Perfect.

Yes, that I get it.

Okay. Yeah. Yeah. I'll jump back in.

Is inhalation and exhalation present at the same time?

That's kind of where I'm going. So think about physical structure. So, narrow ISA bias, he's going to have a lot of volume that will rest downward in the pelvis. And then as it fills up, it spills over the front. And so now you've got inguinal ligament that's under tension and twisting. As the pubis gets compressed backward in a narrow ISA, the angle of ligament is going to twist in opposition of it until it hits the constraint and then it goes with it. We always talk about twisting the towel. You want to untwist that towel to whatever degree that you are capable of doing. So you need to bring the ASISs closer together. That takes tension off the towel and then you create the anterior posterior expansion and that creates the untwist. Does that make sense? Yes. So the shape change is going to be your goal to start. But you've got an internal load that's potentially putting pressure directly on the area that you're trying to alleviate as well. So you're going to have to use positioning. Does he have different symptoms in different positions?

Not really.

Yes.

I'd say he's learned. He's learned, from our standpoint of what we do.

Do you think that she's going to be able to access that space?

Okay.

I was listening to your explanation of concentric and eccentric versus yielding and overcoming. I was thinking about the contrast sets that you would usually do when you would do like a high load, highlighted squat and then into like a plyometric activity or just like jumping. So it's basically like biasing the muscle tissue to a concentric bias and then trying to hold that concentric bias while the connective tissues will yield to explode. So that was basically my only question.

How do you get into a deep squat? Yes, sir. In respect to what?

You know, you think about just the fluid content alone. Under these circumstances, too much tension, not enough fluid in the tendon itself, so it can have normal behaviors. And it's like, okay, well, how do I do that? Is that going to be a load-based response? Probably not. That's going to be the ability to move the connective tissue through its full excursion of compression and expansion just like everything else.

Right. Yeah. What I'm trying to do is find exercise selection that will help me work on their acceleration. I've been doing ipsilateral step ups and making sure they drive forces into the ground and work on tendon stiffness. But I was wondering, am I missing something adductor-wise? Basically, I just don't want to put them too much in contralateral exercises. So I'm probably too much in my own head.

OK, so this is somebody that's going to have a center of gravity that is as far forward as they can probably go, right? So your end game, so your issue of generosity is going to be compressed forward, right? And so it gets closer and closer, and then it becomes in line with the femur. Right? If it would go, if I, if I postally oriented that, that pelvis in that position, I theoretically just magnified that strategy. Right? So you can have to, you literally have to move the issue of tuberosities back. Right? And then I need to create a wider representation of the outlet. Does that make sense? Cause you've got a, you've got an outlet that is, that is compressed and pushed forward. I need to bring the outlet back and then open it back up.

All fours, extend one leg back. That's a bird dog. Okay. What position is that in regards to propulsive strategies?

And do you generally feel like they're forward on the right side as well? But it depends.

All right. So at the higher rate, you're going to see just a narrower total excursion. Right, so it's like, I'm not going to see a positional change that's this big because the movement isn't that big. Right? It's a smaller movement at a higher speed, you understand?

Okay, hang on. So if we're talking about the back leg and the jerk, so left foot lead, right foot back. Okay. So think about them moving through time. So from initiating the dip, okay. They're going to start from middle to max. And then as they split their legs front to back, they've got to go from middle to a delay on the front leg and a late representation on the back leg. So I'm moving from IR. So late has more internal rotation superimposed on it to begin with. Okay, you understand that? So think about which carry would you want that would be more representative of a late representation that has more an internal rotation superimposed on it. So the simple answer would be, you give them a left suitcase carry and you give them a right waders carry. Because that'll turn them as they walk, it will turn them in the same direction that you're trying to turn them in the bottom of the jerk.

Yep. Okay. Yeah, definitely need to sit down.

Gotcha.

So in many of those cases, all they need to do is create some form of compensatory strategy that produces enough external rotation to allow them to descend. What you might see is compensations through the extremities: a wider stance, toes out to create that external rotation space to allow descent, and then it can produce internal rotation at the bottom of the squat. You'll see that in a lot of accomplished Olympic lifters. Or you might see a compensatory strategy that looks like a lumbar compensation that allows descent very comfortably, in fact, into a deep squat but probably not the strategy that we would be looking for. On the other end of the spectrum, if I'm a narrow ISA, that should be capable of deep squatting based on pure structure. If I superimpose enough superficial strategies on top of that axial skeleton, I'm going to create a higher pressure situation that will prevent me from accessing the external rotation that I'm going to need to descend in the squat. So it'll look something like where you will see them sort of hit that hard stop just above parallel where they can no longer descend. The pelvic diaphragm can no longer expand anterior to posterior that they would need to get into the deep squat.

Hold on on the left side. Left side is more forward than the right side.

Not yet. Sorry.

Does that make sense?

There you go. That's the question you have to ask, okay? So classic subjective questioning from physical therapy school, Jordan, here you go. Somebody walks in with shoulder pain, right? One of the questions you always ask somebody is like, can you lay on that side? Okay. Now, why do you ask them if they can lay on their side?

Okay. So now I'm curious how you would test for this to see whether the left or right side is stuck in early or late propulsion. I understand people can become stuck in these phases of propulsion.
