Yeah.

somewhat, yeah.

Okay. I kind of figured that was what was going to be the case, but when you said posterior lower, where?

Okay. But the part where you're holding the sacrum. How would you call that? Because it's underneutation. But would you say that posterior pelvic outlet? Is that a correct term?

That's a really helpful reminder. Yeah.

Okay.

I would start them just above where you would think that the ideal dip representation would be because I don't want them to descend below that because that's what they're already doing.

Well, so part of the thing that you want to recognize as a coach is that you know what you want and they have no idea what you want. Right. So they don't know anything, and it's not that they're ignorant or stupid or whatever. It's just the fact that they don't think like you do. And so they don't have the same understanding that you do.

Yeah. Yeah. Right. And chances are if you took them to 90 degrees for a traditional hip measure, you wouldn't have IR either, right?

Yeah. So I created relative motion at the ankle. It's exactly, you're exactly right. I created relative motion at the ankle. So if I need to teach somebody how to get an inversion ankle spring solid, right? That's a great way to do it.

Dang straight. Exactly. But that doesn't mean that I'm not getting ER at the proximal femur from the get-go. You see the difference?

Water like fluid.

And then you have something to test it against, right?

Yes, sir.

Okay. So Jordan, here's what I want you to do. Get the wall behind you. Okay. Get about six inches from the wall. Just stand in front of the wall.

Exactly. So I'm going to the source. Okay.

Yeah, yeah. So you've got an ER'd foot, right? You've got an arch. That means, so whether we're late or whether we're early, it means you've got concentric orientation that's holding that arch up.

Yeah.

No, chances are you're going to have to give her a little bit of an assist. Okay. To reduce some of the, some of the orientation. Okay. Do you understand?

Squeeze it out.

So something I will see in pretty much every ACL case—more so than other post-op cases—but ACL in general. At some point along the way in rehab, when we start introducing activities like split squats, step downs, or anything vertically moving their center of mass that isn't bilaterally symmetrical, and especially with higher-velocity movements involving single-leg landings—I guess the best way to describe it would be a traditional representation of closed-chain dorsiflexion where they just don't get the knee going forward as much. I'd attribute that early on to anterior knee sensitivity. They describe not wanting to let that knee go forward because the more it bends, the more it hurts. But then at a certain point, they're not really feeling active discomfort, yet they still aren't letting the knee translate forward as much. I was curious your thoughts, especially regarding what we've discussed about the axis of rotation changing. Is this a manifestation of the fact that they just don't have as much local midfoot propulsive representation because they're missing tibial internal rotation? So that makes me wonder if my expectation should be that they just aren't going to get as far without some other compensatory strategy.

Mm-hmm.

Good morning. Happy Friday. I have neuro coffee in hand and it is perfect.

So with the healthy sprinter, at max velocity, the time constraint is so significant that anything that's going to slow that down is problematic. If you're trying to train max velocity with rubber resistance, I would question your thought process. So, I guess that was the last part of the question: from a resistance standpoint, either with acceleration (probably more acceleration), you'll see either elastic resistance or you'll see things like changing directions.

Yes.

Yes, sir. Absolutely. It is. It has to. So, okay, so, and this is one of the reasons why people get stuck—they can't descend. Because the center of gravity just keeps pushing forward because they cannot produce the ER representation with the yielding representation of early. So they can't access early and they can't sit down into a deep squat.

When I looked at the video and I talked about having room back there, and the rest of the description about shifting left in the squat and all the rest of it sounded accurate to what I had here. That's where I came up with the idea that perhaps he doesn't have that at the lower point. I don't think he has much space.

Okay, hang on a second. Are you more likely to capture an earlier representation on asymmetrical stance activity or an asymmetrical stance activity for a wide ISA? Probably asymmetrical. Start there. Okay, start there. That's what I would do if you're, especially if you're struggling, right? So you put her in like a heels elevated thing you go, ah, this is going to give her some space back there. It's like, I already do stagger to see.

Yes, sir. So they're going to lose external rotation on the right side. Would they still have medial foot contacts?

How do you teach a kettlebell clean? You teach a kettlebell clean from the top down. You say, here's the end position. Drop this weight down between your legs and they go, and you go, now just reverse gears. And you just taught somebody a kettlebell clean in 20 seconds. Instead of taking half an hour to give them all the nuances, you just, like I said, start them at the end and then you see what I'm getting at?
