14. Alternating Dumbbell Bench Press: A challenging twist on the classic, lie on a flat bench with a dumbbell in each hand. Hold the dumbbells on the outside of your shoulders and alternately press the right dumbbell up overhead and back down, then the left. This exercise also forces you to engage the core for stability — bonus!
15. Dumbbell Pull-Over: Expand your wings by working the serratus muscles. Get in a tabletop position with shoulders planted on a bench and feet on the floor. Next, hold a dumbbell by one end with both hands straight overhead, engaging the glutes and back muscles. Lower the weight in an arch behind your head until you feel a good stretch. Bring the dumbbell back to starting position.
