Now that your Wii Balance Board is safely tucked underneath the couch and you've long ago discovered that every standard Nintendo title can be played with the flick of a wrist, you might be wondering how you'll ever convince yourself to exercise again. Well, there are certainly a few dangling-carrot solutions to your problem, and here's one that actually makes sense -- the Blaze U-Move, a Nunchuk replacement (with built-in pedometer) that effectively locks your joystick in place. The idea is that unless you're moving, your avatar can't move, and when you do, it can -- each time you jog in place, you're building up virtual momentum. That certainly sounds like a much more graceful and practical solution than others we've seen, which turn off the entire controller or (Miyamoto forbid) cut power to your entire game machine. This way, you can stop running when you need to do some precision aiming, and set your mind at ease regarding your save game. Yours for £20, or about $32 in US currency.
