How To Perform
- 1 Lie on a flat bench with dumbbells held above chest, palms facing each other.
- 2 With a slight bend in the elbows, lower the dumbbells out to the sides in a wide arc.
- 3 Lower until you feel a strong chest stretch — typically when dumbbells are at chest level.
- 4 Return in the same arc, squeezing the chest at the top.
Form Cues
- ✓ This is a stretching movement — do not use heavy weight.
- ✓ Maintain the same slight elbow bend throughout — do not let the elbows straighten or bend further.
Common Mistakes
- ✗ Using too much weight and turning it into a press.
- ✗ Letting the elbows straighten — this shifts load to the biceps and puts the shoulder at risk.
💡 Professor Splits Says:
Progressive overload is the engine of muscle growth. Track your weights and aim to add small increments weekly. For Dumbbell Fly, this means gradually increasing load, volume (sets × reps), or decreasing rest periods over time.
