Tech That Kicks New Year's Resolutions Into Gear

There's always got to be a fitness resolution, right? The Goji Play ($100) itself might not force me into the gym four times a week, but it will make the usual boredom of cardio alley machines fun. From the makers of Guitar Hero, Goji Play works on iOS devices in tandem with a free app that monitors your motion as you exercise through the synced game simulations. Place the included activity sensor somewhere on your person, and either hold or affix Goji Play's two game controllers to a cardio machine while following along with the app on a mobile device, and you'll break a sweat while playing video games.
