Start by standing upright with your feet shoulder-width apart, toes facing forward. If you're new to this move, stand in front of an exercise bench. Clasp your hands together at chest level.
Raise one leg off the floor in front of you (without bending your knee). The heel should be an inch or two off the floor.
Balancing on one leg, sit back to lower into a squat on your standing leg. Let your butt touch down on the exercise bench, if you're using one.
Grounding into your standing foot, engage your glutes to push into a standing position. That's one rep.
