And then because like you're doing so much of that in the way that just becomes like a default strategy for them, even when they're not necessarily moving the heavier weights.

But the duration.

Really?

Okay, cool. So with a wide, I would want to start like above the trochanter and upper DR. Like this is where I want to kind of figure out.

If I recall, you're a narrow stance. I think so. You're a pole vaulter, you're a narrow stance. I think Sergei Bubka was probably the only wide stance pole vaulter I've ever seen. Yeah, he did okay, didn't he? Yeah, he just had a weird structure. Okay, so do your best imitation of like an RDL. Oh, thank you for turning sideways. How perfect. That was great. Solid move, solid move. Okay, so. Just don't think, just do this. This is like quick and dirty. Boom. Okay. All right. So, here's the bad news. You still have a counter-rotated sacrum. Okay. So that was something I would not recommend, but in that position, my point is that your center of mass actually went forward. For you to load your heels, you have to lighten your forefoot. Did you feel that? Yeah. Yeah.

I do, but I'd be hard pressed to get it up on my phone for you. But I might post one. I might post one because she's dead flat. Like DR is flat as a board.

Or anything. Do you have any tests that you do in a seated position for the axial skeleton? Like seated rotation? How useful is that? Now you start to see what the deal is. Why do you do a seated rotation test? Because I need to differentiate between lower extremity mechanics and axial mechanics.

The role of the fibula.

But hang on. All right. So if I'm going up on the left.

Yes. So again, you're looking at energy storage and energy release. Then you're also looking at the position of the outlet that allows you to achieve—like for me to get my leg into the external rotation representation, the pelvis has to change its shape, which means that I'll have an outlet change. It's a lower force producing position, but it started from a very high force producing position. As I move farther and farther away from it, my velocity is increasing. If velocity is increasing, I can't push as hard into the ground anymore, so it's no longer concentric orientation. It's going to transition back to the eccentric orientation.

Not a great force producing position. It is actually a reducing position; that's a position that is reducing its force production. Okay. Which is why when you see somebody lock out with the so-called hyper extended elbows, that's why you don't want to see that.

OK. Yeah. So you build your intention in and you say, OK, I'm going to compare you. I'm going to compare you to the ideal. So I understand what you're doing. And then we will try to move you in that direction to whatever capacity you have without inflicting any unnecessary consequences.

So we need to create a... So it would typically be anterior orientation associated with it, yes.

But this is the thing: for the younger coach or therapist, getting dirty means putting themselves in uncomfortable situations where their decisions may not be the best choice. We do that in a safe manner through supervision, if you will, of a mentor working as an apprentice. That's where you perform safe-to-fail experiments. This is where you learn that you're not always right, your choices aren't always the best, and the outcomes aren't always perfect. We have these discussions. People often present the best-case scenario, sounding like the greatest coach or therapist in the world. But if someone followed you around for a week, they might say, 'You really screwed that one up.' The response is, 'Yes, I did. But you know you're going to survive it because you've got the experience that says, Yeah, I've screwed this up before. I do it a lot less than I ever did.' It still happens because anytime you're interacting with another system, you have no idea what their response will be. Getting comfortable with that takes time.

Can I give you a scenario? Of course. Okay. Two athletes. You're going to test vertical jump. They both jumped to, they both have a 32 inch vertical jump. So it's exactly the same. The first athlete pushes into the ground for 0.25 seconds to get his 32 inch vertical. The second athlete pushes in the ground for 0.35 seconds to get his 32 inch vertical. What's the difference?

Same thing. Okay. So when the knee is at the top of the squat, when the knee is fully straight. Is it fully straight at the top of a squat? No, I guess it's not. I hope not. No.

Yeah.

With the shot.

E-centric.

Yeah, just you go, hey, sit down on the box, stand back up. Almost everybody in the whole world, when you start them on the box and they stand up, they do it the right way, right? And so that's a simplified representation of that. Now, if I was trying to capture a yielding representation on somebody in a box, what would I do? I then pause on the box. Okay, you sit down, they expand, and then they come back up. Right, so that is an expansion and a compression, I'm teaching them in the most simplest of ways.

You see it? Yeah. So again, you just think about like, how would I want to... So if I wanted to bring a foot back to where it was actually squared calcaneus to the ground, I have to push from the outside edge of that heel towards the medial aspect to square it up. Same thing with the ischium under that circumstances. I got to put pressure on the lateral aspect of the ischium to push it towards a normal representation of that, that ischium. Okay. Cause the ischium is bent. The ischium is bent just like the heel is. Now, do you understand the placement?

Okay.

Okay, yes, but I want you to, if you can, explain to me how you would coach somebody to step backwards with a sled that would be coherent with what we've talked about so far.

So whenever I say a bias, what that means is that both representations are present. You're showing more of one than the other. You're biased toward something. So somebody who is biased toward the inhalation, as a behavioral strategy that keeps them a little more biased toward that inhaled representation, they're going to be more ER biased. By structure. So like a narrow ISA has a structure that biases them toward more of an ER representation. So their breathing bias is going to be a lower pressure strategy, which is biased toward an inhale. So their behavior is toward an inhale.

That's correct. There you go. That's exactly what I was saying. So you understand.

If you haven't seen Saturday Night Fever, if you have not seen Saturday Night Fever, you can't be my friend. True story. Grace, I'm telling you, don't be shaking your head, girl. It's like, I know my movies. Good morning. Happy Thursday. I have no coffee in hand and it is perfect.

I would say yes.

So that's going to help you choose what position you're going to put people in.

No, I know that we were already discussing this once and you said that there's no true open kinetic chain. I just wanted to clarify that.

Yeah, so like you're sitting back too far? Yeah. Yeah, so again this is where your coaching cues come into play rather significantly, but I mean, you know, Matt, we're telling an old story here it's like it's always about how you do stuff right. The idea is to understand the principle and then you determine what you think you see and then that determines how you're going to cue this. And so your hand placement, like when we're talking about how you obliques it, your hand placement is going to matter, the direction that your hand is turned is going to matter, the place that you're applying weight bearing, the hip orientation, the lower extremity orientation is going to matter. So I said, do I need more ER? Do I need more IR? Coming from distal to proximal, that's going to determine what type of an obliques that you're going to use.
