Incline Dumbbell Press
With the bench set at about 35 degrees, lie back on the bench, back pressed on the bench, shoulder blades together. Start with the dumbbells either side of your chest, elbows sticking out to the sides. Bring the dumbbells up to a position above your shoulders. Squeeze your chest when you get to the top, but take care not to clang the dumbbells together. By using the incline, you're throwing the effort on your upper chest, for a full, round look.
