Holding the medicine ball with both hands, stand with your feet two to three feet apart. Keeping your chest up, sit your hips back and bend your knees to lower into a deep squat, lowering the ball between your legs (a). Push through your heels and squeeze your glutes to return to standing, bending your elbows to curl the ball in front of your chest (b). That's one rep. Do 20.
