HOW: Loop a heavy band around a sturdy object around hip level. Place your leg through the loop and have the band high on your hip. The tension should be trying to pull your hip outward. Take some steps to the side and find the tension you want. From here, perform a squat by hinging forward at the waist and bending your knees. Find the right squat depth for you and perform as many reps as prescribed.
FEEL: You should feel your leg muscles working as you squat. You should also feel a stretch in your hip from the band pulling it outward.
COMPENSATION: Keep the band high on your hip and make sure there is enough tension on it.
