Hold your hands at chest level, and bend your knees as you shift your hips and butt back, lowering into a squat like you're sitting in a chair. Keep your chest lifted, and do not let your lower back round. Keep your knees over your ankles, and shift your weight back into your heels. Push through your heels to bring yourself back to your starting position, squeezing your glutes at the top of the move. This is one rep. Repeat for 30 seconds.
