HOW: Stand on the step. Shift all of your weight to one leg. With the non-weight bearing foot, you will lunge backward, and then come back up to your starting position.
FEEL: You should feel the thigh muscles and the butt muscles working in the forward leg.
COMPENSATION: Don’t let your knee cave in, and avoid rounding your back or side bending. Make sure you have a slight forward torso lean.
