The interactive-play craze started by Wii Sports has now spreads to your whole body thanks to Wii Fit and the pressure-sensitive Wii Balance Board, which comes bundled with it. Used together players will experience an across-the-board array of fun, dynamic and surprisingly challenging activities, including aerobics, yoga, muscle stretches and balance oriented games. The focus of these activities is towards providing a "core" workout, a popular exercise method that emphasizes slower, controlled motions, but it's the fun approach to fitness of Wii Fit that will keep players hooked on fitness for years to come
