The dumbbell incline fly is an isolation exercise targeting the upper portion of the pectoral muscles. By performing this exercise on an incline bench, you emphasize the upper chest, which helps in developing a fuller, more defined chest. This movement also engages the shoulders and stabilizer muscles, promoting overall upper body strength and stability.

1. Set an adjustable bench to a 30-45 degree incline and lie back with a dumbbell in each hand, held above your chest with your palms facing each other.
2. Lower the dumbbells in a wide arc to the sides, maintaining a slight bend in your elbows.
3. Lower until you feel a stretch in your chest muscles.
4. Bring the dumbbells back together in a wide arc, squeezing your chest muscles at the top.
5. Repeat for the desired number of repetitions, ensuring controlled movement throughout.
