The Nintendo Wii Fit hit the U.S. market on May 19th.  The electronic exercise device has already sold 2 million copies in Japan. It includes the Wii Balance Board, a sophisticated platform that has the ability to sense weight and shifts in balance and in movement.

The Wii Balance Board connects to the Wii console through a wireless connection.  The Balance Board allows the user to engage in up to 40 different exercises including yoga, aerobics, strength training and balance. 

The device features virtual trainers that egg-on the user. The Wii Fit even tracks users’ progress, which lets people see how they have improved while challenging them to better their scores and stay motivated to keep going.

Wii Fit should prove to be a great solution to get gamers off the couch and enjoying the game-like approach to fitness. It should also prove to be a great introduction to Wii for non-gamers who are just interested in exercise. What could be better than bringing interactive entertainment to getting fit.
