A lot of the players that we see attempting to perform side lying hip CARs (controlled articular rotations) show two common difficulties. More often then not, they are unable to maintain a rigid torso and substitute accessory motion in the knee with extension. Remember, the key ingredient to a successful controlled articular rotation is only moving at the joint you’re working on. In this case, you’re trying to isolate the hip! In this video I go over two interventions or tools that we can use as solutions.
I hope that this helps. Feel free to share, comment, and ask any questions!
