Air Squat Stand with your feet slightly wider than your shoulders, feet parallel or toes slightly turned out. Bend your knees, lowering your hips deeply. Bring your thighs parallel to the floor, and bend your elbows, keeping weight back in your heels. Rise back up, straightening your legs completely, squeezing your glutes at the top of the movement to get the most out of the exercise. This counts as one rep.
