Thanks to the hugely successful Nintendo Wii, would-be-flabby video game addicts are getting trim. The clever system uses motion sensors, requiring use of the whole body to play to turn gamers into sporting and action heroes on screen.

Since its launch at Christmas 2006, the Wii has turned many a players' lounge into a virtual tennis court And with the release of countless different games and accessories focussing on getting you moving, the nation may have found its hero to fight against the obesity epidemic.
