Pushup to slideboard mountain climber: Classic mountain climbers are major fat burners on their own, but when you add a pushup into the mix, they become that much better. Now, you get the best of both worlds: calorie-torching and muscle-sculpting. Trust us, you'll be feeling this one tomorrow. For the full circuit workout, check out this page on Furthermore.

How to: Start in a plank position, with gliding discs beneath your feet. Perform one pushup, moving your body in a straight line. Once you reach the top of your pushup, follow it with four quick mountain climbers (bring left knee in toward chest; return to start, switch legs and repeat), keeping hips and spine in a neutral position. Do eight reps.
