Fitness bands have become a dime a dozen, however the Amiigo bracelet differentiates itself by recognizing what specific exercise a user is performing. The band keeps track of type of workout performed, reps, sets, and intensity. It also gages the more common elements like heart rate, skin temperature, and calories burned. It does so by using an algorithm that converts data about acceleration in the human body. The days of people recording reps in notepads at the gym soon will be a thing of the past.
