About Wii Fit:

Wii Fit is a combination of fitness and fun, designed for everyone, young and old. By playing Wii Fit a little every day, you, your friends, and your family can work towards personal goals of better health and fitness.

The Body Test in Wii Fit is a short and simple set of activities used to gauge your body's performance. After choosing a Mii™ - a virtual  caricature unique to Wii - to represent you, use the Wii Balance Board to measure your center of balance, Body Mass Index (BMI), and body control. Based on these results, you can also determine your Wii Fit Age. The whole family can engage in the Body Test and compare their progress together!
