Usually, the only thing you work out while playing video games is your thumbs. Not with Nintendo's Wii Fit. Using a pressure-sensitive balance board, you can transform your living room into a fitness center. Wii Fit calculates your body mass index, then gives you a personalized weight-loss (or weight-gain) plan to help you attain your ideal BMI. There are more than 40 types of training activities, including muscle conditioning, quick cardio, and inventive balance games.
Our fave: ski jumping. To perform the classic winter sport, crouch down and forward on the balance board to pick up speed down the ramp, spring up slightly at the end to gain height, then bend back down to avoid wiping out. Improve your flexibility with the yoga feature. Adopt poses like the half moon and sideways twist, then fi nd out how well you maintained those poses in a postgame evaluation. Do 20 minutes each of cardio, "ski jumping," and yoga, and you'll burn as much as 436 calories in an hour. Available 2008.
Swing the Wiimote like a racket to ace tennis balls, or grip the controller like a bat to swat homers out of the park. The most physically challenging of the fi ve sports is boxing: Use the Wiimote and the Nunchuk attachment as boxing gloves to dodge, weave, and K.O. opponents. Play a "pentathlon"— 12 minutes each of baseball, bowling, boxing, golf, and tennis—for a 433-cal-burning workout. Bundled with the Wii.
