Instructions
Stand upright, grasping a dumbbell in each hand with your arms hanging by your sides and palms facing in. Keeping your upper arms by your sides, raise one dumbbell and rotate forearm until it is vertical and your palm is facing your shoulder. Lower and then repeat on the opposite side.
Tips
This exercise can also be performed by doing the bicep curls simultaneously. When your elbow is fully flexed and palm facing your shoulder, it can move slightly forward allowing your forearm to come up to a vertical position.
