The 90-90 hip exercise is a great exercise that can be scaled down or up in complexity This variation is great for helping hip rotation but also the obliques and lateral hips Take a shin box position and then place your elbow on the ground, similar to when you do a side plank.

For the more complex piece, you will lightly try to lift your hip off the ground
