I love mine. Havent found time for it for a few days, but am really impressed with it. Gradually moving up to harder levels, but I find the jogging the hardest thing to do!
My Wii fit age is hovering around my real age too, so thats not bad. The only thing I didnt like was when it told my 9 year old daughter she was obese. I am not sure if it has a lower age limit, or if it is programmed to take account of age, as such. She is a little chunky, but also very active & going through a growth spurt too, hence a bit of extra weight. There is no way at all she is obese. Me, on the other hand........... definately!!
