1. Lie flat on your back and overlap your fingers behind your head and bend your knees about 50 degrees and keep your feet about shoulder width apart and flat on the floor.
2. Position the right leg above the left leg and start to curl up your left shoulder across your body toward the right knee.
4. Reverse the motion and back to the starting position and repeat.
Tips and Advises:
Your shoulders should come up off the floor only about four inches, and your lower back should remain on the floor.
