NikeFitness Training 360 bundle now shipping, game downloadable on Dec 25
Winter holidays are, statistically speaking, the very best holidays, due to their general abundance of twice-baked potatoes and various pies. But when every serving at every meal contains at least three sticks of butter, those extra pounds can really pile up.

Nike and Microsoft recommend solving your tummy troubles by doing crunches in your living room while a virtual man watches, or as the system is commercially known, Nike+Kinect Training. They've even got an Xbox 360 bundle for it and everything, which includes a 4GB console, Kinect, Nike+Kinect Training, Kinect Adventures and a month of Xbox Live Gold for $250, as seen above. That price tag is only valid through January 5, we should point out. After that, the bundle is kicked up to $300.

Microsoft has also announced that the game itself will be digitally available through Xbox Live on December 25, at a smooth $50/4,000 MS points.
