The decline dumbbell chest fly is an upper-body exercise targeting the muscles of the chest, particularly the lower chest. It will require less weight than a decline press, which makes it a great hypertrophy exercise with high reps. Fly variations are usually performed for moderate to high reps, such as 8-12 reps per set or more.
