Wii Fit
Yes, I too have the Wii Fitness Plus. It is benefical in many ways. Good to start with but have more strenous activities too. There is the "Active" and "Active 2", which are excellent. These give you different levels of fitness. I wouldn't make the Wii my only fitness activity. You want variety so you don't become bored and also you want to work different muscle groups to get all around fitness. Your muscles do become accustomed to the same ole same so you have to give the muscles a challenge too.
