HOW: Begin in a standing position with a slider underneath one foot. Shift most of your weight to the leg without the slider. Perform a small squat by bending your knee and hinging forward at the hips while you slide your foot forwards, laterally, backwards, and back and around. Return to the starting position in between each rep.
FEEL: You should feel your thigh muscles working in the leg that is squatting down.
COMPENSATION: Keep you back upright. Keep the knee that is sliding out straight.
