I just bought a Wii finally on Saturday and broke out the Wii Fit. It's lots of fun. I did some hula hoops, running, tightrope walking, yoga and step.
The Wii Fit makes me laugh because it's so snarky. When I was doing the initial tests, it decided I was very unbalanced. To be specific, it asked if I tripped when I walked. When I turned it on last night to show a friend what it was like, the game scolded me for being up so late, then said "Staying up late can mess up your body's natural cycle. It also doesn't make waking up in the morning any easier." Since I hadn't turned it on the day before (Church and fixing friends' computers) , it then wondered "Too busy to work out yesterday, Nessa?"
I enjoy it so far. I still have a lot to unlock, so I guess I better get crackin' on that. I'm also excited for WiiFitPlus to come out (points for including juggling!). I will also have to check out some of the other fitness games for the Wii. Any suggestions?
