Supinated Curls Details

Hold a pair of dumbbells by your sides with a neutral grip. Rotate your wrists into a supinated position and curl the weights toward your shoulders. Keep lifting until your forearms press up against your biceps. Turn your pinky fingers as far away from your body as you can while you squeeze your biceps. Hold the contraction for a second. Lower the weights under control and twist your wrists back into a neutral position when you reach the halfway point in the eccentric phase of the rep.
