### Full technique — 8 steps

1. Set a decline bench, hook your legs under the pads, and lie back with a dumbbell in each hand.
2. Set your shoulder blades down into the bench and hold the dumbbells over your chest.
3. Keep a slight, fixed bend in your elbows throughout the set.
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. As the dumbbells meet, you can turn your palms to face your feet.
8. 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
- Lifting shoulders off bench
- Bringing dumbbells too far back

## Form cues

- Slight elbow bend, fixed angle
- Stretch, don't force depth
- Match the same arc
- Keep shoulders down and back
- Turn palms as dumbbells meet

## How much to do

- **Strength**: 3–4 sets of 6–8 reps · rest 1 min 45 s · 2–3 reps in reserve · lower 3 s, lift 1 s
- **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.
