Coolly energetic Wii Fit videos to whet your exergaming appetite

If there's one thing we're not lacking, it's Wii Fit videos. From demos to clips of perfect, expressionless trainers getting their exercise on, we're swimming in footage of other people trying out the Balance Board -- and now there are four new videos available for your viewing pleasure. This time, it's a bunch of seemingly regular Japanese folk (who happen to have enormous living spaces, on the Japanese scale) shuffling their furniture and laying down mats to test out Nintendo's latest foray into exergaming. We're starting to think that, with all these videos, we could grab some foam and a few tennis balls and start working out now.
