Heart rate monitoring is the single most accurate means to understand how your body is responding to exercise. Innovative technology means you can get accurate hear rate information without the need for a separate chest strap. Your heart rate is measured through a sensor in the watch that monitors changes in the blood flow in your wrist. This is done by shining a light though the skin and detecting the changing light reflections.
Independent testing has shown that the built-in Heart Rate Monitor is extremely accurate compared to electrocardiography.
