Dumbbell Fly
Technique guide
Set-up
- Lie on a flat bench holding a dumbbell in each hand above your chest, palms facing each other.
- Keep a slight bend in your elbows.
How to do it
- Open your arms out to the sides in a wide arc until you feel a stretch across your chest.
- Stop when your upper arms are about level with the bench.
- Bring the dumbbells back together over your chest along the same arc.
Coaching cues
- Keep the same slight bend in your elbows throughout.
- Move at the shoulders, not the elbows.
Common mistakes
- Lowering the dumbbells far below the level of the bench.
- Bending and straightening the elbows so it turns into a press.
Safety
- Use a lighter weight than you would for pressing: the long arm position loads the shoulders.
