i use wii fit, had a party last night, its fun but can get a bit boring like any exercise, I have changed to rayman raviing rabbids tv party, which is very funny and really gets your heart going with loads of fun games and dancing....the good thing a bout wii, is you can do it not matter what the weather...
I don't know how much differnce it makes,but I'm sure it must make some! I try and go on it most days,for between 20 and 40 minutes, I don't come off feeling like I've been to the gym,but it's 20-40 minutes that I would normally have spent sat on my bum, so I must be burning a bit more fat than normal!!
I've only really being doing it for the last couple of weeks, but I would think it has to speed up weight loss a little........and it's quite fun!!
The Wii Fit weight is just a generalisation and shouldnt be taken insteas of the usual weigh in. Dont forget you are weighing on carpet!
I use mine quite regularly, I concentrate on things such as my posture rather than if the exercise is doing me any good.
I sweat, it gets my heart racing, so it must be doing some good! Its fun and I enjoy it and that the main thing!
