Overhead Tricep Extension: Correct Form & Muscles Worked

Triceps (Long Head) primary Dumbbell Beginner Isolation · Push

The overhead tricep extension stretches and loads the long head of the tricep — the largest head that most pushdowns miss. By raising a dumbbell overhead and lowering it behind your head, the long head is stretched maximally under load. Essential for complete arm size.

How to Do the Overhead Tricep Extension

  1. Sit or stand holding one dumbbell with both hands. Raise it overhead, arms fully extended. Cup the top end of the dumbbell with overlapping palms.
  2. Keep your upper arms close to your head, elbows pointing forward (not flaring out).
  3. Lower the dumbbell behind your head by bending at the elbows. Go as deep as your flexibility allows — the stretch is the point.
  4. You should feel a deep stretch in the triceps at the bottom. Pause briefly.
  5. Extend the elbows to press the dumbbell back overhead. Squeeze the triceps at the top. Don't lock out aggressively.

Overhead Tricep Extension Mistakes to Avoid

Elbows flaring wide — keep them pointing forward, close to your head. Flaring reduces the stretch on the long head.
Not going deep enough — the stretch at the bottom is where the long head gets loaded. If you're not feeling a stretch behind your head, go deeper.
Using too much weight and losing control — the dumbbell is behind your head. Safety first. Use moderate weight you can control.
Skipping overhead extensions entirely — pushdowns alone don't fully develop the long head. The long head is the biggest tricep head. You need overhead work.

Overhead Tricep Extension Muscles Worked

The overhead tricep extension preferentially targets the long head of the triceps by placing it in a stretched position overhead. The long head crosses the shoulder joint and is only fully stretched when the arm is overhead — making this exercise uniquely effective.

Overhead Tricep Extension Alternatives

Cable Overhead ExtensionWant constant cable tension in the overhead position
Skull CrusherWant a lying stretch-focused tricep exercise — similar long head emphasis
Tricep PushdownWant standard cable tricep isolation (but won't fully develop the long head alone)
Dumbbell Skull CrusherWant lying tricep extension with independent arms

Overhead Tricep Extension FAQ

Why is the overhead position important for triceps?
The long head of the tricep crosses the shoulder joint. It's only fully stretched when the arm is overhead. Pushdowns work the lateral and medial heads well but don't stretch the long head. Overhead work is the only way to fully develop the biggest tricep head.
One dumbbell or two?
One heavy dumbbell with both hands is standard. Two dumbbells (one in each hand) allow independent arm work. Single dumbbell is simpler and allows heavier loads.
Seated or standing?
Seated provides more stability and reduces the temptation to use body momentum. Standing is fine too. Seated is recommended for strict form.
Overhead extension vs skull crusher?
Both stretch the long head. Overhead extensions provide a deeper stretch. Skull crushers allow heavier loads. Both are excellent — use either or alternate.
