The Wii Fit has been great at our house. My husband does all of the exercises everyday, plus he is walking and riding a bike. (He would never push away from the computer or TV before) He was diagnosed with diabetes, high blood pressure and high cholesterol, so he decided it was time to do something. I walk with him, but I fall over on the bike so I am out on that one. I bowl, play tennis, golf, yoga and do the balance exercises and I know it is helping. I get dizzy easily so I can't do as much as I would like to do, but I can see a difference. I love how it keeps track of your weight and BMI and how you have to have a password to get to that information!!!
A lot of the nursing homes and senior living places here have them for their residents to use and they are very popular. I must say it is the first "game" I have truly enjoyed and felt is worth the money.
