PULSENSE reads and records your heart rate from the changes in light reflected through your blood vessels. As you exercise, your heart rate will increase. The thresholds for these heart rate zones are based on a percentage of your maximum heart rate. PULSENSE automatically tracks this and tells you what zone you are in.
