This exercise uses cables to isolate and work the triceps (muscles on the back of the arms).
Place an incline bench facing away from a cable pulley.
Attach a short straight bar to the pulley and adjust the height so that your arms can extend fully.
Lie face up on the bench and grasp the bar with a narrow overhand grip.
Keeping your arms straight, slowly push the bar down towards your feet.
Pause at the bottom and then return to starting position.
Note: Keep your elbows steady throughout this exercise.
