Stand facing a cable machine with a high pulley and a straight bar, V-bar, or rope attachment. Grasp the handle with an overhand grip, keep your elbows close to your sides, and push the attachment downward until your arms are fully extended. Slowly return to the starting position while maintaining control and tension in the triceps throughout the movement.
