Incline Dumbbell Fly

A chest isolation exercise on an incline bench using a fly motion to target the upper pectorals. It combines the incline's upper-chest bias with the fly's deep loaded stretch, making it the most direct isolation work the upper chest gets. Placed after incline pressing, it finishes the job with light weight and full range.

Technique

How to Do the Incline Dumbbell Fly

  1. Set the bench to between 30 and 45 degrees and lie back with light dumbbells over your chest.
  2. Turn your palms to face each other and set a slight fixed bend in the elbows.
  3. Open your arms in a wide arc, lowering the dumbbells out and down.
  4. Descend until the stretch peaks across the upper chest.
  5. Sweep the dumbbells back together over you, squeezing as they rise.
  6. Stop just short of touching at the top to keep tension on the chest.

Do This

Form Cues

  • Set the bench between 30 and 45 degrees.
  • Keep a fixed slight bend in the elbows.
  • Open until you feel the stretch across the upper chest, then reverse.
  • Let the stretch settle for a beat at the bottom before reversing. That pause is where the incline fly pays.

Avoid This

Common Mistakes

  • Turning it into a press by bending the elbows.
  • Lowering too far and overloading the front of the shoulder.
  • Touching the dumbbells together at the top and losing tension.
  • Setting the bench too steep, which slides the stretch off the chest and onto the front delts.
