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!

While the Mii is taking the Body Test, sometimes the Wii Fit Board will ask you to close your eyes. It suggests you can also hold an extra item the next time. When your Wii Fit Age is very different from your real age, you may be told to improve your skills or that you have much time to improve!
