## How to do the Dumbbell Flye

3. Slowly lower the weights out to the sides in a wide arc.
4. Bring the dumbbells back up, squeezing your chest as you finish.

### Full technique — 7 steps

1. Lie on a flat bench with feet planted and a dumbbell held above your chest in each hand.
2. Turn your palms to face each other and keep a slight, fixed bend in your elbows.
3. Set your shoulder blades down into the bench and hold the dumbbells over your chest.
4. Lower the weights out to your sides in a wide arc without changing your elbow angle.
5. Descend until your chest is fully stretched and your upper arms reach bench level or slightly below.
6. Bring the dumbbells back together along the same arc by drawing your upper arms inward.
7. Finish with the dumbbells above your chest without letting them drift behind your shoulders.

## Common mistakes

- Turning the flye into a press
- Bending and straightening the elbows
- Dropping too deep at bottom
- Letting shoulders roll forward
- Bringing dumbbells too far back

## Form cues

- Slight elbow bend
- Move through the shoulders
- Stretch, don't force depth
- Match the same arc
- Keep shoulders down and back

## 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 2 s
- **Endurance** (good fit): 2–3 sets of 15–20 reps · rest 45 s · 3–4 reps in reserve · lower 2 s, lift 2 s

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