If you've taken a holiday recently and absolutely let go while at it, here's a simple calorie math: If you want to indulge in a few extra calories, you'll have to sweat off a few more than usual. Send 'em packing with these four explosive moves created by Kim Blake, a trainer at Nike World Headquarters Sports Center in Portland, Oregon. You'll push your body weight off the floor and then absorb it when you land. Translation? Your muscles will work hard, and you'll blast fat.
Do 12 to 16 reps of each move, resting for 15 seconds between each exercise. When you've finished all four, rest for a minute or two, then repeat the circuit two more times.
Do this calorie-incinerating workout three times a week, or anytime you need a little damage control.
