Someone on another board commented that people who purchase this, "need to get off their lazy asses, and go outside."
While, I can agree with that to a certain degree, there is no need to get negative about something that is getting people to exercise. Exercising is good no matter how you get it. If a video game is getting people up, and making them actually use their bodies, I don't see how it could be bad.
That said, I enjoy working out without the aid of wii fit. I am planning on buying a bike tomorrow or the next day, so I can waste time biking. The bike will be more expensive than wii fit, but cheaper than a gym membership.
And to the people who say that people need to just go to the gym instead of being lazy bastards and buying the wii fit. How much would a gym membership + a yoga trainer + a boxing coach + skis + a place to ski cost you? I guarantee wii fit is cheaper.
