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, and know more about body parts.
There are two main modes in Wii Fit: Body Test, and Training. In the body test, Wii Fit will measure your center of balance, and body mass index (BMI), then will give you two balance tests before determining your Wii Fit Age. In training mode, you can select one of 48 activities including yoga, strenght training, aerobics, and Balance games.
