Muscle increases your resting metabolic rate, burning a higher amount of calories—and belly fat—around the clock.
And a healthy weight leads to a healthy heart. A 10-year Mayo Clinic study found that overweight people had heart attacks 3.6 years earlier than normal-weight people did. And obese heart-attack patients tended to be 8.2 years younger than normal-weight victims.

The challenging 30-minute workouts hit every muscle in your body, and create a calorie burn for up to 48 hours after you’re finished. (One guy lost 12 kilos in 6 weeks!)
