This wonderful review on Wii Fit which describes using the Wii Fit Board, successfully to lose weight, has an accurate description of what is required to lose weight.
I generally agree, with these additional comments: the Wii Fit is easy to set up; the assessments are blunt and can be inaccurate; the exercises I do are fun; some of the exercises don’t appeal (yoga, muscle fitness) and I don’t use them because using Wii Fit to supplement my exercise program, I’m not dependent on Wii Fit for strength building exercise.
If you need to be convinced to attend the gym, avoid walking outside and can’t imagine doing it inside, then the Wii Fit program can offer you many options for fun ways to get moving. I like the jogging as a warm up. The step games work as activity particularly if you are counting steps but of course in general a long walk outside would give better results. I weigh in monthly. You can even do this without knowing your weight at all, which I like. I have had 2 weigh ins with one loss and one gain. I haven’t taken the gain too seriously as muscle build up can add weight
As a general policy when exercising to lose weight I enthuse about what is working for me and ignore what isn’t. Often that means that some process or piece of equipment may be imperfect but some of it isn’t, so it’s worth persevering. Walking itself comes into that category. I supplement my weight loss program with the gym, Wii Fit, games, ipods, dvds, friends, forums.
Wii Fit has some limitations in that the already slim or active, who are looking to tone or trim, may expect too much from it. It is definitely aimed at the inactive and overweight where some activity, with gradual increases, will produce results.
