Nintendo, the make of the Wii phenomenon, is taking their virtual world one step further. Earlier I told you about how retirement communities were using the Wii technology to get residents to be part of bowling leagues – increasing opportunity for exercise and social interaction.

According to a USA Today article, in May 2008 Nintendo will roll out the Wii-Fit Balance Board, a small platform where users can exercise, stretch and do yoga with on-screen avatars — all designed to help keep you fit and lose weight.

The Wii Fit product will also include access to the “Wii Fit Channel,” an interactive online channel that lets users check in daily to track fitness progress through weight and body mass index (BMI).
