Overview

Cable One-Arm Overhead Triceps Extension is a unilateral exercise that has you extend the elbow while the upper arm stays fixed overhead. Holding the arm in this overhead position places the triceps under a deep stretch, which helps create a stronger contraction as you lift. Because you work one side at a time, this movement is useful for building even triceps strength and sharpening muscle definition.

How to do it

  1. 1

    Setup and Starting Position

    • Fasten a single handle to the low pulley on a cable machine.
    • Stand with your feet about shoulder-width apart and take the handle in one hand.
    • Face away from the machine, then bring the handle overhead with your elbow bent and kept close to your head.
    • Brace your core and keep a neutral spine for the entire exercise.
  2. 2

    Execution

    • Straighten your elbow to press your arm fully overhead.
    • Contract your triceps hard at the top.
    • Lower the handle back to the start slowly and with control.
    • Complete 3 to 4 sets of 10 to 15 reps, then change arms.

Form tips & common mistakes

Hold your elbow still so you do not rely on momentum.

Move with control instead of jerking the weight.

Keep your lower back from arching; brace your core to stay stable.

Choose a light to moderate load so you can focus on form and muscle contraction.

Keep your wrist neutral to avoid strain.

Benefits

Isolates the Triceps: This exercise targets the triceps brachii effectively, supporting better muscle growth and definition.

Corrects Muscle Imbalances: Because you perform it one arm at a time, it can reveal and help fix strength differences between sides.

Enhances Muscle Control: The cable keeps tension constant, which increases muscle engagement and control through the full motion.

Reduces Joint Stress. Compared with free-weight triceps extensions, the cable version provides a smoother, more joint-friendly range of motion.

Improves Overhead Strength: This exercise builds strength in the lockout phase of overhead pressing, which carries over to bench press, shoulder press, and dips.
