Forearm Supination from Neutral With Resistance

In this video, the action of controlled lowering of the weight is an eccentric muscle contraction. The motion of moving from a neutral position to a palm up position is forearm supination. Eccentric forearm supination is demonstrated with the elbow bent to 90⁰ of flexion starting from a neutral position and ending in a fully supinated wrist position as seen from a front or anterior view.
