The chest muscles are used in daily activities, such as pushing a stroller. The inclined dumbbell fly is also commonly used for overall strength development in the chest muscles. This exercise focuses on the pectoralis major, which is the scientific name of the main area of the chest being worked.

Begin by sitting straight up on an incline bench, the weights resting on your thighs. Lay back on the bench and bring the weights directly above your chest, palms facing together. Keep a slight bend in your elbow, then slowly lower the dumbbells out to your sides until the dumbbells reach chest level. You should feel a slight stretch in the chest. Slowly raise the dumbbells back up to the starting position. Exhale as you raise the dumbbells. You must keep the angle of your arms the same during the entire movement to effectively perform the fly.
