Incline Dumbbell Press is a great exercise for working your chest, especially if you have shoulder problems while using a flat bench. Make sure you keep your elbows back and your wrists tight. Push up focusing on your chest, keeping your shoulder blades tight against the seat. Lower the weight slowly using your chest muscles to resist. If you are using heavy weights, be sure to have a competent spotter. Focus hard on your chest muscles, its easy to use your triceps too much.
