Dust off that Balance Board, because you're going to need it for Wii Fit U. Much like the first Wii Fit game, Wii Fit U is all about getting active in order to live a healthier lifestyle. Wii Fit U includes new exercises and games designed to get you in shape, and (using the Balance Board) it can track your weight and BMI so you can keep track of your health as you play the game.
Nintendo is also releasing a Fit Meter that you can wear to track your activities and workouts throughout the day. The meter tracks how many calories you've burned, how many steps you've walked, and the types of exercises you've completed, and it syncs all that data with Wii Fit U wirelessly.
