One Arm Tricep Extension with Cable

Muscles worked

The prime mover is the triceps brachii, which straightens the elbow, and through its long head helps pull the arm back at the shoulder.

How this movement works

One joint moves, and it moves the load away from the body. With nothing recruited to assist, the target muscle reaches its own limit rather than the limit of the weakest link in a chain — which makes this useful for adding volume after the heavy compound work, not for opening a session.

It is filed under strength: produce force against resistance for a countable number of repetitions, and progress the resistance over time.

What you need

A cable holds tension for the whole range, including the point where a free weight would go slack. Moving the pulley changes the angle the resistance arrives from without changing the movement.
