Overhead Cable Triceps Extension

A triceps exercise using a cable machine with arms extended overhead, emphasizing the long head of the triceps. The cable keeps the long head loaded through its full stretched range, including the bottom position where dumbbells go light. For pure long-head stimulus per set, this is arguably the best triceps exercise in the library.

Technique

How to Do the Overhead Cable Triceps Extension

  1. Set a rope attachment on a low or mid pulley and face away from the machine.
  2. Bring the rope overhead so your elbows point forward, beside your ears.
  3. Split your stance and lean slightly forward for balance against the cable.
  4. Let the rope pull your hands back behind your head into a full stretch.
  5. Extend both arms overhead until straight, separating the rope ends at lockout.
  6. Return under control to the stretched position and repeat.

Do This

Form Cues

  • Face away from the machine with the rope overhead and the elbows beside your ears.
  • Keep the upper arms fixed. Only the forearms move.
  • Split the stance so the cable cannot pull you backward.
  • Set the stretch first, then extend. Every rep should start from the deepest comfortable position.

Avoid This

Common Mistakes

  • Letting the elbows flare out wide.
  • Leaning too far forward, which turns it into a pressdown.
  • Cutting the stretch short at the bottom.
  • Turning it into a shoulder press by letting the elbows drift wide and the shoulders take over.
