How to Do a Reverse Crunch

Tips & Warnings:

• For an easier reverse crunch, lift one leg at a time while the other leg's knee is bent and its foot is flat on the floor. You can also use your hands to help you lift your hips. Just remember that it's an abdominal, not arm, exercise.
• Advanced exercisers can use hands behind the head or arms extended above the head. A medicine (weighted) ball between your knees can also add to the challenge.
• Exhale as you lift and curl. If the exercise seems too easy, you're probably not doing it correctly. Slow it down and really control the movement.
• To show off your new, toned muscles, you may need to shed a layer of fat. See "Lose Weight," under Related eHows.
• There are multiple variations of the abdominal crunch, including pull-down and cross-knee crunches--see Related Sites for details.
• Lying on an exercise mat rather than a hard floor helps prevent back strain.
• Despite what you may think, commercialized abdominal machines/rollers are not enough to get you solid abs. A "six-pack" results not only from crunches, but also consistent aerobic and fat-reducing exercise (such as running), as well as eating a low-fat diet.
• Avoid arching your back. Relaxing your abdominal muscles during this exercise will result in back extension (arching), putting tremendous strain on your back. If you can't avoid arching, strengthen your abdominals for a few weeks with a regular crunch before performing this exercise. (See "Do an Abdominal Crunch," under Related eHows.)
• If you have any condition that would impair or limit your ability to engage in physical activity, please consult a physician before attempting this activity.
