The truth is you can't turn one type of tissue into another. But you can burn more fat and build muscle with short, intense bursts of exercise that raise your heart rate and get your body working as efficiently as possible.

This type of high-intensity training over a short period of time can actually burn more fat than moderately-paced, longer cardio sessions. The key to a workout like this is to strap on a heart rate monitor and keep your heart rate at 80% of your target. Try this 15-minute workout every day to start seeing real results.
