As anyone who's managed to get their hands on a Wii will no doubt have already discovered, it's relatively easy to work up a sweat and lose some pounds using Nintendo's little white box. Now, the real life activity that's required to succeed at virtual Wii Sports has been picked up on by a personal trainer from Glasgow, Scotland: Zander Urquhart found that kids and adults alike don't mind doing exercise when it's accompanied by on-screen actions by the player's Mii, and is using the Wii specifically as an exercise machine. Zander is apparently the first fitness expert to have seen the potential for the Wii in the field of personal training, but we have a strong feeling he won't be the last. Even if the idea doesn't catch on, we suspect he'll have a healthy stream of geeky customers coming into the gym as long as the Wii stock shortage continues to exist (which, judging by the sporadic shortages of the 10 month old DS Lite, could be some time yet). Be honest with us: have you lost any weight thanks to your Wii?
