There’s a new time and place for exercising in Japan. The time? Always. The place? Your crotch.

Ladies and gentlemen, behold the Calorie Shaper.

Just how does the Calorie Shaper work? No idea, we don’t speak Japanese. The dude in this video is reasonably fit though, and apparently getting fitter by the moment, by simply going about his regular day which consists of choreographed dance numbers in a surreal world of animation and nonsense. That’s scientific enough for us.  The Calorie Shaper must be the real deal!

So forget going to the gym or eating right, that is so early 2011. Let the Calorie Shaper do the work. Simply throw this high tech pair of  spandex biker shorts on and let the undies do the work for you.
