Two-Hand Overhead Dumbbell Extension: how to do it right
In short: Elbow extension with your arms overhead, holding one dumbbell in both hands, to hit the triceps under heavy tension in the stretched position.
How to do it, step by step
- 1Standing or seated with your back upright, hold the dumbbell in both hands in a cupped grip, arms straight overhead, elbows tucked in toward the front.
- 2Let the dumbbell lower behind your neck by bending only the elbows, humerus vertical and still.
- 3Go for the full range, until you feel a strong stretch on the back of your arm, without forcing the shoulder.
- 4Control this lengthening phase over 2 to 3 seconds, with no bounce at the bottom.
- 5Come back up by straightening the elbows, without locking them out violently.
- 6Keep your elbows stable the whole time, they must not flare out.
The mistake to avoid
Don't let your elbows flare out to the sides, keep them tight.
Other common mistakes
- Flaring the elbows out to the sides, which unloads the triceps and stresses the shoulder; keep them tucked in and pointing at the ceiling.
- Lowering too fast or bouncing at the bottom, which steals the stretched tension and hammers the elbow; brake over 2 to 3 s with no jerk.
- Arching your back as you press the dumbbell, which cheats with the trunk; brace your abs and lock down your ribcage.
- Going too heavy and losing range; lower the weight so you reach the full stretch under control.
Muscles worked
- Main:
- Triceps
The triceps brachii is the prime mover, with a clear emphasis on the long head, which attaches above the shoulder joint and is pre-stretched when your arms are raised. The lateral and medial heads help extend the elbow. The anconeus assists at the end of the range. The shoulders and trunk stabilize the top position.

Frequently asked questions
How do I do this exercise?
Standing or seated with your back upright, hold the dumbbell in both hands in a cupped grip, arms straight overhead, elbows tucked in toward the front. Let the dumbbell lower behind your neck by bending only the elbows, humerus vertical and still. Brake the descent, then straighten the elbows again without locking them out violently.
How far down should I go?
Lower the dumbbell behind your neck until you feel a strong stretch on the back of your arm, that is where the long head works the most. Don't rush this bottom zone, it is the most productive one. Go for the full range you can control, not the one you reach by squirming or flaring your elbows.
I don't feel anything, is that normal?
You should feel the long head pulling behind your arm in the bottom position, dumbbell behind your neck. Think of the exercise as a loaded stretch, not a press. Slow the descent, keep your elbows fixed and tucked in: if you flare them, the triceps gets unloaded. A slow tempo with a moderate load feels way better than a heavy, sloppy weight.
How fast should I do the movement?
Brake the descent behind your neck over 2 to 3 seconds, with no bounce at the bottom. Then come back up firmly but under control as you straighten the elbows. It's the braking in the stretch that does the work, not the speed on the way back.
How should I breathe?
Breathe in and hold before letting the dumbbell lower behind your neck, it locks the trunk and protects your back. Keep your abs braced throughout the lengthening. Breathe out as you straighten the elbows upward. Never relax your bracing in the bottom position, that is where the load pulls the most.
