I was on the Livestrong website when I came across this morsel of information: Apparently you must reduce your body fat to about 8 percent for a man and 14 percent for a woman in order to reveal your abdominal muscles. Isn't that interesting? I never knew it had to be that low. To read more, visit the Livestrong website.
