Dumbbell incline fly

Set an incline bench to a 45-degree angle. Sit on the bench with a dumbbell in each hand, palms facing each other. Lie back on the bench and press the dumbbells up to the starting position, directly above your chest. Lower the dumbbells out to the sides in a wide arc until you feel a stretch in your chest. Pause for a moment, then squeeze your chest muscles to bring the dumbbells back up to the starting position. Repeat for the desired number of repetitions.
