Grasp a broom handle, stick, barbell, or similar object with both hands. First with palms up (supination of the forearms) and then with palms down (pronation of the forearms), perform a biceps curl (flex the elbows from the anatomical position of elbow extension to the position of full elbow flexion). Note the difference in the feeling in your forearms, wrists, and hands when the curl is performed in forearm pronation and forearm supination. What causes the difference when the forearms are in pronation at the beginning of the movement? ●
