Bridge Chest Press- Lie on your back with your knees bent and feet flat on the floor. Hold an 8-12 pound dumbbell in each hand, keeping the weights directly above your chest with your palms facing away from you. Press your hips off the floor until your torso forms a straight line, and contract your abs to hold yourself still. Next, press the weights straight up above your chest and then lower them, repeating for a set of 12. Lower your hips after each set.
