Plyometrics -- or high-intensity exercises that stretch and then quickly shorten your muscles (think jump squats or plyo push-ups) -- are already known for their quick calorie-blasting, body-toning results. "The technique was originally designed to develop explosive speed and power in Olympic athletes, but the benefits extend out to the average Joe and Jane in both body and mind," says Adam Rosante, NYC-based trainer and creator of the popular bodyweight interval workout WaveShape. "The intensity of firing up your big muscle groups with such speed sends your heart rate through the roof and burns a ton of fat." Plus, Rosante explains, when your brain is forced to process the mechanical speed required of plyo moves, it has the potential to improve overall cognitive function.
But there's better news yet: There may be an even more efficient way to do this powerhouse type of workout.
