Alternating Incline Dumbbell Curls

Sit on an incline bench and hold a dumbbell in each hand with your arms hanging down at your sides and your palms facing in toward your body. Slowly curl the dumbbell in your left hand up to shoulder level, while rotating (i.e., supinating) your wrist so that your thumb ends up pointing away from your body at the top of the movement. Squeeze your bicep at the top for a one-count and then slowly lower the weight back down to the start position.
