Performing the: A Step-by-Step Tutorial Lever Triceps Extension
Stand with your feet shoulder-width apart and grasp the bar with an overhand grip, hands also shoulder-width apart.
Bend your elbows and bring the bar down until it's about level with your forehead, keeping your elbows close to your head and your upper arms stationary; this is your starting position.
Extend your arms, pushing the bar down and away from your head, using only your triceps, until your arms are fully extended but not locked.
Slowly return to the starting position, resisting the pull of the cable as you do so, to complete one rep.
