Jumping Rope

It may seem like little girl stuff, but there's a good reason that heavyweight boxers also make use of jump ropes. It's a serious hardcore workout. Not only can jumping rope burn about 200 calories for only 15 minutes (800k an hour), but it increases agility, tones your muscles and gives you powerful strength.

Running

Take a good look at the mallwalkers in their track suits on Sunday. Do any of them have the body you want? No, it's the runners who look long, lithe and muscular. That's because a mere 20 minutes of sprinting burns almost double the calories of a whole hour of strolling. Speed up your time around the block and you'll burn about 700 calories an hour.
