Wii Fit

I got one... It wasn't very easy to find either. I found out you needed the board to play some other Wii games so I figured why not. I tried it. It's a lot harder than it looks. And it does make you break a sweat if you do it long enough. The fun thing about it is that you move around and play to be top score all at the same time. So if you're competitive, and like to win, it may motivate you to move faster, which in turn burns more calories. Sounds like a win-win situation to me.
