1 - Set a cable pulley to a high position and attach a single handle or use the cable end without an attachment if preferred.

3 - Keep your elbow fixed near your torso, your chest up, and your core braced with a stable stance.
4 - Start with your elbow bent, then extend your arm downward and across your body until your elbow is fully straightened.
5 - Squeeze your triceps briefly at the bottom while keeping your shoulder and upper arm as still as possible.
6 - Slowly return to the starting position under control without letting the weight stack slam.
7 - Repeat for the desired number of repetitions, then switch sides.
