Tricep extension

Cable rope pushdown

What it works

Works

Triceps

Equipment

Cable

How to do it

  1. Attach a rope to the high pulley and grip one end in each hand.
  2. Keep your elbows close to your body and a neutral grip.
  3. Extend your elbows by pushing down and spread the ends apart at the end.
  4. Squeeze your triceps at the bottom, keeping your elbows still.
  5. Return under control until your elbows bend to 90 degrees.

Common mistakes

  • Moving the elbows forward while pushing
  • Leaning the torso too much
  • Not spreading the rope ends at the bottom

What the evidence says

Over 12 weeks, training one arm overhead and the other with the arm at the side, the overhead arm grew about 1.4–1.5 times more: +28.5% vs +19.6% in the long head and +19.9% vs +13.9% in the whole triceps — and that with lighter absolute loads. If you only keep one extension variation, make it the overhead one.

In trained lifters, eight weeks of doing only the lengthened half of the range produced the same elbow-extensor growth as full range of motion. The non-negotiable part is the bottom, the stretch: you can cut the lockout without losing anything.

At 0° of shoulder elevation the triceps long head generates the most force; from 90° upwards the medial head takes over as the main elbow extensor. So the overhead position isn't where the long head contributes most — and it's still where it grows most.

What isn't settled: What's well measured is shoulder position (overhead vs at the side). What isn't is the comparison between the actual variations: nobody has compared lying EZ-bar extensions vs cable pushdowns vs kickbacks over time at matched volume. The kickback in particular has no growth study at all — only the suspicion that it loads the triceps at its shortest length.
