## How to do the Alternating Dumbbell Shoulder Press

1. Sit on the bench with your feet flat on the floor, holding a dumbbell in each hand.

4. Lower it to shoulder height, then press the other side.

### Full technique — 7 steps

1. Sit tall on a bench with back support and plant both feet firmly on the floor.
2. Hold a dumbbell in each hand at shoulder level with elbows under wrists.
3. Tighten your stomach and keep your ribs in line with your pelvis without leaning back into a big arch.
4. Press one dumbbell upward until that arm is extended overhead, keeping the other at shoulder level.
5. Lower it back to shoulder level along the same path.
6. Press the other dumbbell the same way and keep alternating arms.
7. Keep your back against the bench without leaning toward the working arm.

## Common mistakes

- Leaning toward the working arm
- Overarching the lower back
- Stopping short of full overhead extension
- Letting dumbbells drift too far forward
- Shrugging shoulders during press

## Form cues

- Keep forearms vertical
- Keep ribs down
- Press straight overhead
- Stay against the pad
- Press without shrugging

## How much to do

- **Strength** (good fit): 3–4 sets of 5–8 reps · rest 2 min 30 s · 2 reps in reserve · lower 2 s, lift 1 s
- **Muscle growth** (best fit): 3–4 sets of 8–12 reps · rest 1 min 30 s · 2–3 reps in reserve · lower 2 s, lift 1 s
- **Endurance** (good fit): 2–3 sets of 15–20 reps · rest 1 min · 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.
