Okay. That's cool.

I'll check it with you. That one is here.

You ever seen somebody that's described as a sway back? Looks like their pelvis is like way ahead of their knees. Yep. That's kind of what you're looking at when you've got a stroke patient like that. So they create a delay strategy so they can push down into the ground because they don't have the capacity to pressurize on that side. They can't create this IR representation. They can't create the concentric orientation of the outlet to push into the ground. So what they do is they create a quick delay at the knee which drops the knee behind the center of gravity. Now their body mass can push down into the ground. That's how they create the downforce when you can't create a downforce.

So I think. I've seen people pull it so that it pulls it in further. That would be leading resistance. Right. And so then the goal is, with that resistance, to push your leg outward. But I feel like if you're being pushed forward, you know, like I feel like that's being, first of all, it collapses because you're being pushed forward on that side, say like left side. And so then that might, so that solution might not even work in that case.

Yeah, you're producing the internal rotation at the femur rather more distally.

Okay.

Yes. All right. And for the Camperini deadlift, how would I use it in someone I'm trying to push right to left? And would that actually be the left foot back and epsilon load, which, because of the left foot back, left foot, left hand load? Back up one baby step.

I don't learn.

Yeah, you keep saying that, but I keep having weird measures for it.

This actually builds on a conversation or a series of conversations that we had on some of the Coffee and Coaches conference calls and a couple of other calls where we've been talking a lot about internal rotation and the representations of how we're taking force from the ground and then reapplying it to the ground and what shape changes need to occur. So those of you playing the home game let's take a look at the pelvis real quick. So we're talking about the IR representation of the pelvis here and remember that we can drive this in two different ways. We can drive it from femur into the pelvis so we have internal rotation that's coming up from the ground through the hip into the pelvis to promote the shape change or we have the proximal shape change first and then we're driving the internal rotation down back into the ground so we have early and late representations of internal rotation. And so we talked about sled drags, how we can manipulate the belt position to help us influence each one of those. And with Manuel's question, what we did is we took it to a split stance. So Manuel's a weightlifting coach, he talks about split jerks a lot, but we can use this in any split stance activity where we'll see the competitor strategies that come up from the ground with the compensatory strategies that we're delivering to the ground. And then we can start to determine how we're going to structure a coherent program. So if we were using sled drags again as the example, how we're going to position the belt, how we're going to cue the activities to promote whether we're influencing intramutation coming up from the ground or down from the pelvis. So thank you Manuel for this question. It's going to help a lot of people.

Yes.

So I think I understand middle propulsion conceptually. I understand that it's a position of internal rotation applied directly down. There's no external rotation or force from the back going down or from the bottom going up. It's this moment in time of pushing directly towards the body and lifting from the ground.

So if let's just say that you've got somebody doing a straight-up side plank who can't do it on the ground, you elevate them. So now their arm is up on a box—on a big, high box. So now your ground contact becomes the elbow and the hand, right? Same rules, but it's just a different sensation.

So here's what you do. You do the wedding march backwards with the sled, stepping back with the right leg only. So you go step back on the right. Left leg comes to even. Step back on the right. Left leg comes to even. Step back on the right. Left leg comes to even. You do that first. The way that you know that you're going to be successful is you're going to pick up IR on the right side. You got to do that first.

Yeah.

Yeah, I'll picture it.

Thumb is there. So that's going to push the talus towards you. See it? Grab the calcaneus. I twist it this way. I'm pushing with my thumb. You see it? So I create them. I create a mid-tarsal representation with one hand. I'll back it up here so I have leverage so I can get the mid-tarsal and the first mid-tarsal into the right position as well.

No, I guess not.

Is there any way you can take advantage of the, because, like in that, in the motion, moving from let's say right to left, take advantage of the

And when you say, when you say inner, where are we?

Okay.

Probably get some weird looks if I tried that.

Yeah, I see that too. So to me, that seems like you're kind of compressing from both sides. I think about the toothpaste example. So it is this way.

If it was more oblique, I think it would be more the left side going further forward, up and over.

All right. So let's think about this. What is the intention of the strategy regardless of which direction you're going? What is the intention with that strategy? You mean like with the exercise or what are they trying to increase as they're performing that stretch? Say it out loud, well, go ahead.

Yeah, that makes sense. Grossly as you move through from early to middle, while the bias of location changes, is it still?

Yeah, exactly. So now you know, so there you go. It's like, if you start to see these compensatory strategies and you consistently see somebody missing a lift, it's not, it's like, okay, you know where you got to go. It's like, this is not a matter of coaching technique. This is a matter of like, okay, you just bumped into a constraint that we have to resolve first. Now we go back and now that maybe the technique is perfectly fine.

Yeah.

Nope.

Right, because they would have, again, just looking at this really oversimplified, like standing in one place model, they would have less of a lumbar lordosis, wide ISA. And so that shape would be, would be, no? Okay, very much.
