I played the wii for almost for a night straight and it wasn't tiring at all. You most have to be seriously out of shape and well ******ed to need the wii to help you lose weight.
What does being ******ed have to do with any of that?
But I agree...I'm a big guy, and it dosen't tire me out...boxing is a ****** but other than that, I don't see how it could help anyone.
