Stand facing away from a cable machine with a straight bar attached to a high pulley. Grasp the bar with an overhand grip and raise it overhead. Keeping your elbows close and upper arms steady, bend at the elbows to lower the bar behind your head. Then extend your arms fully to return to the start, focusing on slow, controlled movement to maximize triceps activation.
