## How to do the Dumbbell Overhead Triceps Extension

1. Stand holding a dumbbell vertically with both hands.
2. Extend the dumbbell overhead, positioning it just behind your head.
3. Slowly bend your elbows, lowering the dumbbell as far as comfortable.
4. Straighten your arms, pushing the dumbbell back up overhead.
5. Keep your upper arms still and elbows pointing forward throughout.

### Full technique — 7 steps

1. Stand tall, holding one dumbbell vertically with both hands under the top plate.
2. Press the dumbbell overhead and position it directly above or slightly behind your head.
3. Keep your upper arms mostly fixed and elbows pointing forward rather than drifting wide.
4. Inhale and bend your elbows to lower the dumbbell behind your head as far as your mobility allows.
5. Stop when your forearms fold underneath and your upper arms stay in position without your ribs flaring.
6. Exhale and extend your elbows to drive the dumbbell back overhead until your arms are straight.
7. Finish with the dumbbell directly over your shoulders without leaning back or letting the elbows flare.

## Common mistakes

- Elbows drifting too far outward
- Turning it into a press
- Arching the lower back
- Cutting the bottom range short
- Letting upper arms swing

## Form cues

- Keep upper arms fixed
- Lower behind the head
- Elbows point forward
- Straighten fully overhead

## How much to do

- **Muscle growth** (best fit): 3–4 sets of 8–12 reps · rest 1 min 15 s · 2–3 reps in reserve · lower 3 s, lift 1 s
- **Endurance** (good fit): 2–3 sets of 15–20 reps · rest 45 s · 3–4 reps in reserve · lower 2 s, lift 1 s

Reps in reserve: how many more you could still do when you end the set.
