I don't know if I can. So, all right. So you have a direction. Let's use the IR. Can we do that? Can we use the IR representation? OK. So as I'm descending into the squat, I have the IR that's going to be coming this away. And so what happens is this is going to compress downward right here. I'm going to increase the load on the femur. That's going to start to bend this because I got to bring IR. It's actually in a squat. It's going to go this way and then towards the center. So it's going to make like an L. L-shaped there like that. So as I descend in the squat, I put more pressure on the head of the femur. It's going to change its angle. So as I change this angle, it's going to create a force against the pelvis. And for me to maintain pressure, I have to push back against it. You see it like that? I have to push back against it. So there's the IR coming up from the ground. Yes. So I started, so I'm standing, I start my descent. I got to put pressure down on. So this is why, this is why the sacrum has to push forward. Like the illing has to move forward because I got to push down on the femur so I can, so I can create an IR position to bring the, the internal rotation centrally. And so I get a shape change through the femur that comes up to promote the shape change into the pelvis. You see it? So I put pressure there. That allows the IR to come this way. I got to push back against it. There's the IR representation there. And then I get the pressurization of the outlet coming up. I get the nutation of the sacrum to squeeze. And then there's my higher pressure representation. As I descend past that, if I want to keep going in the downward direction, the IR representation is going to stop me. That upward pressure is what you use to get out of the squat. So I got to let that go. If I let the motor output decrease, Dante now knows that if I reduce the motor output, I have greater potential for yielding in the connected tissues. That's what happens at the bottom of the squat. And I go back into my ER representation, which is that. To get out of the squat, I got to push this back up so that pelvis will do this. So I can push the IR back down into the femur and stand back up. So in the descent, the IR is coming this way. In the ascent, the IR is going that way.
