Weight & Reps
Dumbbell
The incline dumbbell fly isolates the upper chest with an emphasis on stretch and contraction. Set the bench to 30-45 degrees and control the weight through the full range of motion.
How to Do Incline Dumbbell Fly
- Set the bench to 30-45 degrees with dumbbells held above your upper chest
- Open your arms in a wide arc, feeling the stretch across the upper chest
- Keep a fixed, slight bend in your elbows — your arm angle should not change during the rep
- Bring the dumbbells back together above your upper chest, squeezing the inner chest

Common Mistakes to Avoid
- Letting the dumbbells drift down toward your belly instead of keeping them over your upper chest
- Straightening the arms at the bottom of the movement, which stresses the bicep tendons
- Rushing through the eccentric (lowering) phase instead of taking 2-3 seconds to stretch

Frequently Asked Questions
What muscles does the incline dumbbell fly work?
The incline dumbbell fly primarily targets the clavicular (upper) head of the pectoralis major and the anterior deltoid through an isolated stretch-and-squeeze motion.
How much should a beginner incline dumbbell fly?
Start with 8-15 lb (3.5-7 kg) dumbbells per hand. Incline flys are lighter than flat flys because the angle reduces your mechanical advantage. Focus on control and stretch.
Incline dumbbell fly vs incline dumbbell press — which is better?
Incline press allows heavier loads and builds more overall upper chest strength, while incline flys provide a superior stretch and isolation. Use presses for strength and flys for hypertrophy and finishing sets.
