So we've got a few people that have lifted heavy things on the call and they can attest to this, is that as you get better at lifting heavy things, you get better at squeezing yourself. Okay, so these are the superficial strategies that we talk about that create the anterior posterior compression. Okay, so if I squeeze you front to back, your socket orientation—so shoulders and hips—becomes oriented into extra rotation so they face sideways more so than they used to. And so that biases you into a position of ER. So this is not relative motion ER as we would want throughout the pelvis and the thorax. This is just an orientation. So it's just a socket position that's biasing this. Because of the anterior compressive strategies that you've used and evolved through lifting heavy things, you now compress the front side of your body and that takes away your internal rotations. So you're biased into ER orientation, and then you lose your relative motion internal rotation. Anterior compression. And then any internal rotation that you do have is going to be an orientation towards the ground. So this is people that would typically have an anti-orientation to the pelvis or an anti-orientation to the thorax. Does that make sense?
