Wrist-Based Heart Rate Readings
While chest straps are often regarded as being the most accurate reading of your heart rate and its variability, they can be a bit clunky, uncomfortable, or ill-fitting (either falling off or cutting off your circulation). But with the Fitbit Surge, you can make sure you’re maintaining the intensity of your workout, or make sure you’re working within a certain heart rate zone thanks to its automatic wrist-based heart rate monitoring. *Talk to your doctor to find out which heart rate zones are right for you, and what the appropriate range is. For example, a moderate intensity zone can improve basic endurance and burn fat; a high intensity zone can help you improve cardio performance; and a maximum intensity zone can be used at a higher fitness level for interval and endurance training. You can set a target heart rate zone to make sure you’re pushing yourself hard enough, but not overtraining.
