Dumbbell Incline Chest Fly
- Beginner
- Dumbbell
The dumbbell incline chest fly isolates the upper portion of the chest through a wide arc instead of a press. By keeping the elbows soft and opening the arms out to the sides, the chest is loaded under deep stretch at the bottom and squeezed hard at the top — without the triceps and front shoulders taking over the way they do in a press.
How to do the Dumbbell Incline Chest Fly
- Set a bench to a 30 to 45 degree incline and sit with a light dumbbell resting on each thigh.
- Lie back with a dumbbell in each hand, palms facing each other, and arms pressed straight up over the chest.
- Set a slight bend in the elbows and hold that bend fixed for the rest of the set.
- Lower the dumbbells out to the sides in a wide arc until you feel a deep stretch across the upper chest.
- Pause briefly at the bottom with the chest open and the shoulder blades pinned back into the bench.
- Squeeze the chest to bring the dumbbells back together overhead, stopping just short of touching.
Muscles worked
- Primary:
- Chest
Why train it
- Isolates and builds the upper chest with minimal triceps assistance.
- Loads the chest through a deep stretch for hypertrophy stimulus.
- Improves the mind-muscle connection on a press-dominant chest day.
Common mistakes
- Bending the elbows mid-rep, which turns the fly into a sloppy press and loses the chest isolation.
- Going too heavy, which forces the elbows to collapse and stresses the front shoulders.
- Crashing the dumbbells together at the top instead of pausing for a controlled chest squeeze.
- Pulling the shoulder blades off the bench, rolling the shoulders forward and risking shoulder strain.
