Incline Dumbbell Fly tutorial

The incline dumbbell fly is an isolation move on an incline bench that opens and closes the arms in a wide arc, loading the upper chest through a full stretch. It is ideal for shaping the upper chest after pressing work and suits intermediate lifters.

How to perform

  1. Set the bench to about 30 degrees and lie back with the dumbbells.
  2. Hold the dumbbells over your chest, palms facing, elbows slightly bent.
  3. Retract your shoulder blades and keep your chest slightly lifted.
  4. Open your arms in a wide arc until the dumbbells are level with your chest and you feel a stretch.
  5. Squeeze your chest to bring the dumbbells back along the same arc.
  6. Pause briefly at the top without clanking the weights, then repeat.
Breathing: Inhale as you open your arms and exhale as you bring them together.

Key tips

  • Keep the elbow angle fixed throughout.
  • Imagine hugging a large tree.
  • Use lighter weights than for presses and focus on the stretch.

Common mistakes

  • Bending and straightening the elbows, turning it into a press.
  • Lowering too deep and straining the front of the shoulder.
  • Using heavy weights with fully straight arms.
Safety: People with shoulder problems should shorten the range or use a cable crossover or pec-deck machine.
