Gadgets like the Nike+ FuelBand, Fitbit Ultra and BodyMedia Fit Link use accelerometers, altimeters and algorithms to track everything from how many steps you took to how many calories you burned. By providing this data instantaneously, and in some cases allowing you to share it via social media, they do more than inform. They reinforce, motivate and reward by turning exercise into a game.
Erik says: I now owns a FitBit and I'm activily monitoring my steps while teaching and dancing. I highly recommend this product since it allows you to see your activity level and make adjustments to improve your life.
