Sit on a stability ball with your feet hip-width apart, holding a weight in each hand. Raise your arms above your chest and bend your elbows to a 90-degree angle, lowering the weights behind your head. Pressing the weights up toward the ceiling, straighten your elbows, then slowly bend elbows back to starting position. Repeat for reps.
