Flexion out of the equation. It doesn't exist. It's not there. All we have here is internal rotations. You have a representation of an arm overhead, okay? That has been defined in the traditional sense as flexion. Okay. How many different ways can you get your arm over your head?

If you want to come to a stop, if you decelerate, you're going to need ER.

Right.

Other than the leg.

Yeah.

So how do I get from the right heel to the left heel?

Yes. Okay. So you're talking about the offset load on the left. So you're using a left foot forward split squat offset load. You're moving into the cut. So you're descending into the split squat. You're going to encourage the accumulation of internal rotation, which would promote the shape change that we're after.

And thus more quality or more options.

Okay. Break out your favorite anatomy book and start looking at the stuff that crosses through there. And you go, OK, I have to reduce that muscle tension. I don't have enough eccentric control to allow the normal capture of internal rotation. That's why you can't get proper foot contact. It's because I don't have internal rotation that's coming through the foot from heel to forefoot. I got internal rotation that's stopping right at that first metatarsal phalangeal joint. It's going too fast. I got to slow it down. Well, how do you slow it down? I have to get the relative motions back through the entire foot. Once you get that rotation back, now you capture proper foot contact. Now you get a tibia that will actually turn into internal rotation and allow the knee to bend. But until then, don't try to bend your knee.

Well, you can turn it in that direction, but what's going to happen is you're going to drag everything with it. So the knee, the femur is going to try to follow the tibia. You're not going to get as much relative motion with it because chances are it's going to go too fast, right? The IR is going to. When you have a foot that looks like this, you don't have the relative motion in the foot, which is why you're seeing the adaptive representation of the foot. And so it's just going to drag the femur into IR with it. The goal is to get the relative motion, which is why I'm saying you have to slow down a little bit. Make sure that you get the foot representation first, then translate the tibia and see. You have to stack it up because if the foot goes as a single entity, so is the knee. You're not going to get the differential that you want. Okay, yeah, I was also thinking about this in terms of wide ISAs going up and then coming back down to where their center of mass regionally was.

I'm with you. Yeah. So when they breathe, you'll hear them.

Yeah. So let's say like once, like once the tibia is getting like you're like mid-P. What's the wave doing there? And so, like the calcaneus would be hang on. Yeah. Where's the expansion? It'd be like in the medial part of the subtalar joint and like the mid-foot. Yeah, it's what's back here.

Presumably if you've gotten to a point where you're working into that early representation of the bottom of the squat, like potentially preceding that at some point, you had a ball between their knees working on the middle range and they've demonstrated the ability to capture that on their own.

Just using a Y exercise example, if you're potentially working with a Y where you're increasing their impulse, just watching the ground contact and the ground contact peak force and the result and just making sure that as the ground contact decreases, if the peak force decreases too much, you would see a drop off in height.

When you look at movement efficiency, the ability to go from peak force to low force to no force, there's your velocity. I always go back to Stu McGill's work on this where he was studying martial artists and kicking. He had them wired up with EMG sensors on their trunk, and I believe it was George St. Pierre. There are two peaks of force output in such a movement. When they initiate the kick, there's a very high force that disappears because the leg is moving through space very quickly, which requires as little force as possible. Then at contact, there's another peak force. So you have to view it from that perspective: I need you to be able to ramp up the force very, very quickly and then shut it down very quickly, then sustain it for whatever you determine is the optimal time frame.

Yeah.

There is no ideal. Okay. What you want is adaptability, right?

Hmm.

Bends.

Guys, one more follow-up back to just enforcement. Thanks a lot, Alex. Go ahead. Highline versus funnel.

Tactic tissues, neighboring joints, gravity.

Right? Yeah. Right. What if it's going to take a period of time? Like what if you're not going to be able to get it to the point where you're at phase two, but they just need symptomatic relief from the left knee?

Thank you.

Okay, so I had a quick question about how to get some expansion with a pylon person, you know, with a pyloning athlete. Especially with the athlete that we were talking about earlier, who was pyloning. Given that they have such a compressive strategy that's pushing them down, how would I start, or at least what should I consider for a pylon that you know, compared to say a different kind of archetype or representation.

All right. So I had a question, trying to get a better understanding of how energy is traveling through the system with respect to waves. I'll give a bit of context for why I started thinking about this, which might help answer it. There was a football kid that I had five minutes with him before he had to go out to practice. He came in with lateral hip pain and medial knee pain. The knee pain was more so with even a single, mini squat type motion, and the lateral hip pain occurred when going into a change of direction into the left side, then back out to the right. The pain is on the right side.

So my question is the delay was describing the connective tissue, right? So the delay means yielding on a connective tissue. But how the yielding of connective tissue can change the muscle activity.

So with your experience when you get some pretty decent end game narrows that I've been trying this on, does it normally make them better at it over time with practice? As far as you know, at the moment it's taken them a few minutes before we start to see that effect take place. If making changes correctly then we should hope to see that decrease in time as they get along. Is that generally how that works?

I get that. I think I didn't do a good job asking initially, but that last question of like, differentiate in between those two scenarios and that was helpful.

Theoretically, yeah, that you could look at it that way.

Go ahead. Sure.
