In a split squat, having the tibia behind the foot is standard because you're in an external rotation representation for early propulsion. This position is typical for the beginning of propulsion. If the movement ends in that position, it's because the individual lacks internal rotation. Without access to mid-propulsion or internal rotation, they must descend toward the ground in an external rotation representation. Without internal rotation, the pelvis remains externally oriented away from the lead foot. This results in the pelvis not changing shape, leading to compensatory strategies in the rear leg.

I go, Matt, can I bring those pictures up?

Yeah.

Yeah. Okay. So the reason they're anteriorly orienting most likely is because they can't access that superimposed IR.

Good morning. So I have a procedural question. For example, let's say you're trying to bring a Y back on the right and you want to do like an early Nemo on both sides.

But in that video set, the ear means like that. So yielding means like that. If it's just like this is a dumbbell and they go down, it cannot overcome the weight. So that is yield, right? Yielding behaviors.

Yeah, yeah, yeah.

Oh, yeah, because the elbow is, like, pretty on you. OK.

When did they say to do it? What's the presentation? What's the presentation with that technique is successful?

You move in the direction of expansion.

To a degree until you hit that point at the bottom where it has to yield, then it's going to externally rotate just like you would if you were stepping forward. So the backward movement of the tibia that you would see, like if you're standing to someone's side and you see the tibia go forward as they squat and then it drops back because it's following the sacrum, right? So the tibia and the sacrum are moving back together. The reason that it's moving back from that two-dimensional view is because it's externally rotating again. It's doing the same thing that the sacrum is doing. The sacrum is expanding back into external rotation. It's the expanded representation of the sacrum. The tibia is going to move into its external rotation representation. It's an early external rotation representation.

I hope so. So that, so does that mean if I, if we get better on the counter movement, that means we have better connective tissue behaviors and it's better or good for relative motion? No, no. OK. Connective tissue behavior, hang on. The reason that you have connective tissue behaviors in the first place is because you actually stopped the relative motion and the connective tissues keep moving. This is why static stretching does not improve range of motion to any significant degree because it's not supposed to. It's connective tissue behavior. Muscle orientation, so the change in the concentric to eccentric orientation of a muscle is what changes a joint position. That improves range of motion. See, they're confusing things because they're not paying attention to what's actually happening during the stretching element, which would be the yield. OK, stuff move. No question about that, but it's not relative joint motion. Like you don't, like when you're, when you're trying to train connective tissues, you don't want relative motion because I need the connective tissue behavior to be the stuff that moves joints.

Center of gravity is back.

Are you asking about specific side or just?

Yeah.

Yeah. Yeah. Really good. So this is, this would be in the, because when you, when you're doing the, the rack splits by right, you're shifting weight back on the same side, and then to the left. It's kind of coming like that. And with the propulsive sequence of your narrows, that's kind of where the, when you put the foot down, the center of mass goes up and to the left, if I'm on a right, and then it comes back around.

All right. Does that make sense? Thank you. Yes, sir.

Well, you might not have that motion. I'm just showing you.

We did, not this exact situation. So I'm trying to use my intelligence here. It's OK.

So he has more IR on that left side coming up?

Okay, so this is where the cues come into play to make sure that you go in the appropriate direction. This is why we talk about the foot cues so much when you're using like a grounded representation where the foot's on the ground and supported somewhere as a representation of the ground. This is why the cues become so important is to make sure that you do go in the appropriate direction. So if I want to go right to left in a narrow ISA, the medial foot cues become essential because it will assure me that I'm going right to left. If I didn't capture a heel, you're going forward because you're still in a late representation.

Yeah, they still have to push against the stuff that's going on internally. Right. So what you're going to end up seeing gradually is, the anterior orientation is going to be greater on the left side than it is on the right side. So there's a differential between the two. The further they go, the more you're going to get the anterior orientation going up the right side as well. So again, this is why when you're on the oblique, the left side goes up, and the center of gravity shifts back towards the right. So it's turning on the oblique this way. And as they move forward, there's more and more anterior orientation on the right side. So that's why I start to lose the IR because I'm IR-ing in the spine. I'm not IR-ing in the hip.

All right, so I know for a couple of weeks now we've talked about some of my old school stuff that we used to do, like box squats, and how it's affected in your model. Now one of the things we used to do a lot of sled dragging, and I've seen a lot of your videos on sled dragging, and I'm trying to understand the influence of what we do to your model. So let me give you an example. So obviously I train with a lot of wide stances, just the nature of the beast, right? So we use like a three-inch nylon toe strap to pull with. We do a lot of backwards sled pulling with where we put the nylon strap, let's say around the trochanter, right, where it's a trochanter. We use a load light enough that we can breathe really well. We internally rotate the femurs about five degrees, put the foot pressure all in the arches, I mean in the medial part of the arches, and drive back. Yeah. Is that creating a shape change for the wide stances that are out wide because of the two parts because of the compression that we're putting on the sides?

It's gonna prolong the middle representation, right?

Go ahead.

As I twist a hip into ER or IR, if you could see the tension lines in all of the tissues. When I'm twisting a hip into ER with the hip at 90 degrees relative to the table, outward direction, you should be able to see the tension lines pulling from the right shoulder towards the left hip. You would see it coming from the other side of the pelvis towards the left hip. You would see it coming down the left side to wrap underneath and around. You're seeing the whole system creating this tension, which is what you're measuring. You're measuring the entire system's ability to allow the tissues to move through excursion. Rather than just looking at the hip joint movement, you have to see that everything else is contributing. The degree to which everything can contribute determines the movement outcome. If you take your hand, bring your thumb into opposition, and grab the skin like this, pinching it, and then don't let go of the skin while trying to open your hand up, it's restricted.

I said that I do now.

Okay.

Yeah, sure. But would it actually influence connective tissue behavior? Like in anticipation of the lift, I would actually pre-store energy.

They're not fast enough. Why aren't they fast enough?
