How to do the standing low-pulley one-arm triceps extension
- Grab a single handle with your left arm next to the low pulley machine. Turn away from the machine keeping the handle to the side of your body with your arm fully extended. Now use both hands to elevate the single handle directly above the head with the palm facing forward. Keep your upper arm completely vertical (perpendicular to the floor) and put your right hand on your left elbow to help keep it steady. This is the starting position.
- Keeping your upper arms close to your head (elbows in) and perpendicular to the floor, lower the resistance in a semicircular motion behind your head until your forearms touch your biceps. Tip: The upper arms should remain stationary and only the forearms should move. Breathe in as you perform this step.
- Go back to the starting position by using the triceps to raise the single handle. Breathe out as you perform this step.
- Repeat for the recommended amount of repetitions.
- Switch arms and repeat the exercise.
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.
Even with a single joint doing the moving, the muscle is not working alone — the chest adds pushing force at the shoulder; the deltoids stabilise the shoulder and add force at the top of the range.
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.

Difficulty
Listed at intermediate level. It assumes you already own the underlying pattern and can hold position under load — if the position breaks before the target muscle tires, drop back to a beginner variation until it does not.
