7. Alternating Incline Curls

Lie down on a bench that is set to a 60% incline. Hold the dumbbells with a neutral, steady grip with your palms facing in, and slowly contract your right bicep until it reaches chest level. Then slowly raise the weights, keeping your upper arm tight to your body and gradually rotating your palms externally so that it ends up facing the ceiling. This move is great for building up biceps.
