HOW: Shift your weight to one leg. Bend that knee and hinge forward at the waist to perform a single leg squat. Go as low as you can and then push into the ground to return to the starting position. At the top of the squat raise your heel up all in one motion. FEEL: You should feel your calf, glutes, and thigh muscles working the most. COMPENSATION: Don’t lean to either side while performing the squat. Exercise Library
