Information about the number of calories burned, number of steps, location, heart rate, and heart rate variation can be very useful for cardio training but for strength training you need a different set of metrics. PUSH, a fitness tracking device packed with an accelerometer and gyroscope, uses special algorithms to measure reps, sets, force, power, balance, speed, explosive strength, one rep max, volume load, and tempo. It tells you when you need to stop or when to put in more reps when you lift weights. Essentially, PUSH helps you get more out of your training. Professional sports teams in the NFL, NHL, MLB, and European soccer leagues are already taking notice and they've more than reached their funding goal at Indiegogo.
