Lie on your back on the floor using your lower abdominal muscles to keep your lower back on the floor. Bend your knees at 90 degrees and keep your feet flat on the table. Cross your arms over your chest. Turn your head and trunk to the right as you turn both knees to the left. Allow your knees to relax and go down without forcing them. Bring knees back up, and head to center. Reverse directions. Do five sets of ten repetitions for each side.
