I have a Wii Fit. I love it. I have the Wii fit plus only at the moment, but I am planning on getting some other fitness based ones as well
I use wii fit all the time and it dose work i have lost about 10kgs so far. For me its more about the fact of a night time while my hubby is at work it only me and the kids and the kids want go walking with me because they are young so while they are sleeping i do my wii fit and if its raining or to hot outside then its so much better for me
