If this fat-blasting move is bad, then we don't want to be good.

Tough guys do it in public.
Even Michelle Obama has confessed to it.
These days, it seems like everybody has the urge to burpee.

Beg your pardon? Burpee exercises--aka "The Prison Workout"--are famous for delivering full-body results anytime, anyplace (which is what makes them so popular among equipment-challenged inmates).

So what are you in for? Click here for a video demo or follow these simple instructions. And get ready for some heart pounding: the move, which is similar to a squat-thrust, not only offers a killer cardio workout, but also blasts fat and helps develop balance, agility, speed, endurance and muscle tone (we're talking flat abs, cut arms and tight legs).

What's the sentence? Start getting the benefits of burpees by doing 10 in a row, then work your way up to 20. Incorporate them into your routine by doing a set in between your usual exercises.

Final verdict: This move is all pros...no cons.
