PurePulse Heart Rate is a new technology at Fitbit that we’re really proud of. Included in both the ChargeHR and Surge, it offers continuous, automatic, wrist-based heart rate and simplified heart rate zones. Tracking your heart rate allows you to accurately track your calorie burn, maintain workout intensity, maximize training, and optimize your results. But how do you use it?
