Heart rate is the key to understanding how your body is performing. Continuously monitoring your heart rate through cycles of training, sleep and recovery provides insights that will greatly improve your performance. The AmpStrip gets rid of the uncomfortable chest strap and inaccurate watches. It\u2019s a small, thin, sensor filled strip that you can wear on your torso 24\/7. It continuously monitors your heart to provide feedback about your athletic performance and recovery, helping you find the edge between too little and too much training. It\u2019s smart so that you don\u2019t have to remember to push start or stop or tell it what you are doing, it just knows.
