Overhead triceps extension: how to do it on a cable and why it hits the long head

Published October 19, 2026

Clip a rope to a cable set low or at head height, face away from the stack, and hold the rope ends behind your neck with your elbows pointing forward. Stagger your feet, lean slightly forward, and straighten your arms until your hands are out in front of your forehead. Bend your elbows back until you feel a deep stretch in the back of your arms, keeping your upper arms still.

How to do the overhead cable triceps extension

With your arms overhead the long head of the triceps, which also crosses the shoulder, is stretched as far as it goes, and training a muscle in that stretched position is one of the best ways to grow it. The cable keeps tension on through the whole rep, including the bottom where a dumbbell gets light. It pairs well with a pushdown, which loads the triceps with the arms at your sides.

Steps

  1. Attach a rope to a cable set at head height or the lowest notch, grab the rope, and turn so your back faces the stack.
  2. Step forward into a split stance so the cable is pulled tight, and lean your torso slightly forward with the rope ends behind your neck and elbows pointing ahead.
  3. Keep your upper arms close to your head and straighten your elbows, pushing the rope forward and up until your arms are straight out in front of your forehead.
  4. Spread the rope ends slightly at the end and hold for a moment.
  5. Let your hands travel back behind your head slowly until your forearms touch your biceps or you feel a strong stretch, then extend again.

Cues

  • Elbows point forward, not out
  • Only the forearms move
  • Deep stretch, every rep

Common mistakes

  • Letting the elbows flare wide: keep them about shoulder-width so the triceps, not your shoulders, extend the arm.
  • Moving the upper arm to help the weight: if your elbows drop and rise with each rep, the lats and shoulders are pressing, so lighten the stack.
  • Cutting the stretch short: the bottom of the rep is the point of the exercise, so lower until your hands are well behind your head.

Muscles the overhead cable triceps extension works

The overhead extension trains all three heads of the triceps, and it loads the long head hardest because raising your arms overhead stretches it. The long head is the largest part of the triceps and the one a pushdown with your arms at your sides loads the least, which is why an overhead movement and a pushdown together cover the whole muscle.

Sets, reps and reps in reserve for the overhead cable triceps extension

GoalSets × repsRIRRest
Build muscle 3 × 10–15 1–2 90 s
Most triceps growth work sits here; add a rep or a plate on the stack when you top the range.
Heavier triceps work 3–4 × 8–10 1–2 2 min
Use the split stance and a forward lean so your balance does not limit the set.
Last exercise of the day 2–3 × 15–20 0–1 60 s
Take sets near failure; the cable makes it safe and the stretch keeps it effective at light loads.

Cable vs dumbbell overhead extension

Both stretch the long head the same way. The cable keeps a steady pull through the whole rep, so the top, where your arms are straight, still has tension; with a dumbbell the top is almost a rest. The dumbbell is the better pick when there is no cable station, and the seated version needs nothing but a bench and one dumbbell.

Low pulley or high pulley?

Both work. With the pulley low, you start by bringing the rope up over your head and the cable pulls straight down along your back. With the pulley at head height and a forward lean, the cable pulls back and the stretch is easier to control. Use the one that lets you keep your elbows still; if your shoulders feel pinched with your arms overhead, try the higher pulley and lean forward more.

Questions

What muscles does the overhead triceps extension work?

All three heads of the triceps, with the long head working hardest because your arms are overhead.

Is the overhead extension better than pushdowns?

Not better, different. The overhead extension stretches the long head more; pushdowns let you go heavier with less shoulder strain. Doing both covers the triceps fully.

Should I do overhead extensions seated or standing?

Standing in a split stance is standard on a cable. Seated is easier with a dumbbell and keeps you from leaning to help the weight.

Why do overhead extensions hurt my elbows?

Usually the weight is too heavy for the deep stretch, or the elbows flare. Use a lighter stack, slow the bottom, and keep elbows about shoulder-width apart.

How many sets and reps should I do?

Two to four sets of 10-15 reps with 1-2 reps in reserve works for most people, alongside one pressing or pushdown movement.
