With obesity—especially amongst kids—growing by leaps and bounds, we think this is a great device for gamers young and old. It’s Gamercize Sport, an exercise device that hooks up to your video game console. The catch? The controller only works while you’re exercising. If you stop moving, the controller stops working, so if you want to reach 100% completion on Vice City, you’re literally gonna have to sweat it out. You can hook up Gamercize to your own exercise machine, or purchase their Power Stepper or Mini Cycle. Currently Gamercize is only compatible with PSOne, PS2, Gamecube, and Xbox, however look for Gamercize Pro-Sport in the future, for use with the PS3, Xbox 360 and Nintendo Wii. Gamercize Sport is available for $80 USD.
