As you stand back up, press the weights above your head, then bring them back to the starting position. Do 8-12 repetitions.
Holding a dumbbell in one hand, lie facedown on an incline bench and let both arms hang. Pull the dumbbell up toward your midsection as you keep your elbow close to your body, and then lower the dumbbell back to the starting position. Do 8-12 reps. Switch arms and repeat.
