So a few have you have asked about my Wii Fit!
Yes! It was worth the extra money. Yes! It is super fun. Yes! It is totally addictive.
I love love love it. I credit the Wii Fit with breaking through my stall. The first time I used it, I was sore in places I didn't even know I had the next day. But I went right back to it that night. There are fun games as well as some damn hard exercises.
If you can find one (or are willing to pay high internet prices) I highly recommend buying one! If you hate it, you can always sell it. They are in high demand.
