I just love my Wii fit. I got it for my birthday and the kids and I are having a blast with it. It is harmless competition (which Dylan is winning at the moment) and they are having a blast playing it. Just now we have been doing the "Hula Hoop" and my heart rate is up. Cool huh!!!! It also can track your weight and it tells you when you are losing. I lost this last week. Yea!!!
