Wii Fit Plus details:
Wii Fit attracted millions of new players to the world of video games. Now Wii Fit Plus offers a range of new features and enhancements to help players reinvigorate their workouts, along with exercises and balance games designed to keep them fun.
Players will find a new dimension to the Wii Fit experience as they easily set their own customized workout routines or choose 20-, 30- or 40-minute workouts based on how much time they have available. Users will also be able to choose from specialized workout routines that focus on an individual’s personal fitness goals or certain target areas. And with the addition of activities like Skateboarding and Rhythm Kung Fu, players will be using the Wii Balance Board accessory in a variety of new and fun ways.
