Stand with your feet shoulder-width apart. Hold your hands comfortably in front of your chest to help you stay balanced, or for more of a challenge, place your hands behind your head. Keeping your weight focused in your heels, bend your knees, lowering your hips deeply so your thighs are parallel with the floor.
Press through your heels to rise back up, straightening the legs completely and squeezing the glutes at the top of the movement to get the most out of the exercise.
