Jillian Michaels, of Biggest Loser fame, is bringing out a Wii game...Fitness Ultimatum 2009.
I think it will be out in Australia in the middle of November.
Apparently it uses the Wii Fit Balance Board.
According to the website:
Burn Calories, Get Toned, and
Feel Great With:
* 11 Kick-Butt Activities
* 4 Workout Types (Weight Loss, Strength Training, Interval, Hill Climb)
* Multiple Difficulty Levels (Light, Medium, Hard)
* Support and Motivation From TV’s Toughest Trainer
* Multiplayer Functionality
* Wii Balance Board Compatibility*
It looks cool!
