Lie on your back and bend your knees about 60 degrees and keep your feet flat on the floor. Place your hands loosely behind your head. Curl up and bring your right elbow and shoulder across your body while bring your left knee in toward your left shoulder at the same time. Reach with your elbow and try to touch your knee. Do one side for all your reps,then switch to the other side. Try to bring your shoulder up towards your knee rather than just your elbow.
