So much for video games being easy. Thanks to Nintendo's Wii Fit, you can turn your living room into a virtual gym.

Wii Fit can calculate your body mass index (BMI) and then provide you with a customized workout plan to help you achieve what it also calculates to be your ideal BMI. Using a pressure-sensitive balance board, Wii Fit allows you to enjoy over forty types of physical fitness based games. From ski jumping to yoga, the Wii Fit makes a home workout, dare I say, fun.

But, you'll at least have to wait until after this holiday season to find the Wii Fit, as it will not be hitting stores until 2008. Until then, maybe you can play some of the current Wii games that are available. Research from a UK study revealed that playing active games on the Wii for thirty minutes a day can improve cardiovascular health and help a person lose up to 27 pounds over the course of a year.
