So you've been doing tons of crunches to get rid of your gut, and you feel the difference. But you've got to press through a layer of flab to feel it. What gives?

Even if you do your ab work out every day, you're strengthening your belly, but not doing anything about the layer of fat above your washboard stomach.

The answer? To lose the fat you have to combine all those abdominal crunches with some cardio. Do 30-45 minutes at 70-80% of your maximum heart rate 3 times a week. Curious to know what your maximum heart rate is? Check out Fit's Calculator for the answer.

Burning calories, doing your crunches, and eating a sensible diet will have you seeing your fabulous abs in no time.
