The dumbbell chest fly is an isolation exercise that stretches and contracts the chest (pectoralis major) through a wide arc, with the front deltoids assisting. Performed lying on a flat bench, it builds chest width and stretch under load that pressing alone tends to miss.

Chest Fly - Arms (WRONG-RIGHT): So führst du sie aus

  1. 1Lie flat on the bench with a dumbbell in each hand, feet planted on the floor and your shoulder blades pulled down and together.
  2. 2Press the dumbbells up over your chest so your arms are extended and your palms face each other.
  3. 3Set a slight, fixed bend in your elbows — roughly 15–20° — and lock that angle in place for the whole set.
  4. 4Lower the dumbbells out to the sides in a wide arc, leading with your upper arms and keeping that fixed elbow bend.
  5. 5Stop when your upper arms reach about chest level and you feel a stretch across your chest, without letting the elbows straighten or collapse.
  6. 6Squeeze your chest to pull the dumbbells back up along the same arc until they meet over your chest.
  7. 7Finish your reps, then bring the dumbbells to your thighs and sit up under control to set them down.

Technik-Tipps

  • Keep the same soft, slightly bent elbow angle from start to finish — the arms stay fixed and the movement happens at the shoulder joint, not the elbows.
  • Keep your shoulder blades retracted and pressed into the bench so the chest does the work instead of the front of the shoulders.
  • Use a controlled tempo, especially on the lowering phase, to load the chest through the full stretch.
  • Pick a weight you can arc with clean form — flyes load the shoulder in a stretched position, so going too heavy invites injury.

Häufige Fehler

  • Letting the elbows straighten into locked arms at the bottom, which turns the lift into a long, dangerous lever that strains the elbow and shoulder.
  • Bending and re-extending the elbows during the rep so it becomes a press instead of a fly, which takes tension off the chest.
  • Lowering the dumbbells too far past chest level, which over-stretches the shoulder capsule and risks injury.
  • Letting the shoulders roll forward off the bench at the bottom, which shifts the load onto the front delts and away from the chest.

Häufig gestellte Fragen

What muscles does the dumbbell chest fly work?

It isolates the chest (pectoralis major), which drives the dumbbells together through the arc, while the front deltoids assist. It is not a triceps movement because the elbows stay fixed.

How much should I bend my elbows on a chest fly?

Set a slight, fixed bend of about 15–20° and hold that angle the entire set. Straight, locked arms overstress the joints, while bending and re-straightening turns the fly into a press.

How low should I lower the dumbbells?

Lower until your upper arms reach roughly chest level and you feel a stretch across the chest. Going deeper than that over-stretches the shoulder and adds little to the chest.

Chest fly vs chest press — what's the difference?

A fly is an isolation arc with fixed elbows that stretches the chest; a press is a compound push that bends and extends the elbows and also recruits the triceps. Flyes build stretch and width, presses build pressing strength.

How many sets and reps should I do?

Because it is an isolation move, 3–4 sets of 10–15 reps with a controlled tempo works well. Keep the weight moderate so you can hold the elbow angle and full arc on every rep.
