5UPPER ABS: Extended Leg Crunch
Lie down with your legs extended and your arms bent behind your head.
Exhale, and take two counts to lift your shoulder and chest. Inhale, and take two counts to lower your shoulders to the point where they almost, but do not quite, touch the floor. Immediately continue with the second rep.
Make sure that you do not pull on your neck; concentrate on relaxing your head back into the palms of your hands and on keeping your chin up as you lift.
