The decline dumbbell bench press is a variation of the decline bench press. By using dumbbells during a decline bench press, you allow yourself for a greater range of motion during the exercise. Using dumbbells also requires a great deal of shoulder stability, thus it recruits more muscle fibers to stabilize the body than its barbell counterpart.
The decline dumbbell bench press is a chest exercise that also indirectly targets the shoulders, triceps, and core. The decline angle used during a decline dumbbell bench press is useful for those attempting to build the lower part of their chest.
