Dang I wish I would have seen this thread before I posted my own. It is called Kick butt Wii routine thread.
I love this thing and have lost almost 17 pounds and dropped two jean sizes.
As for the cost. I looked at it this way. I spent 300 on a year Gym membership that I could get to maybe three days a week and had to work out with everyone else. Now I can work out daily and by myself. Changing it up.
The Wii will pay for itself. Plus like someone else mentioned when we have kids over it gets used all the more.
I hope they come out with a Yoga routine game. That would be awesome.
