FINISH: Pull your abs in away from the floor to stabilize the muscles in your entire torso, then bend your right knee to bring your calf perpendicular to the floor. Hold, then straighten your leg, lower your body and rest. Then repeat, alternating sides.



Safety Tip: If your lower back hurts, build up to this exercise by first doing it resting on your knees with just your hips and torso raised and lifting each knee an inch off the floor. Hold for five to 10 seconds and work your way up longer holds and raising your entire body off the floor.
