Those days of getting a heart rate reading only when you visit your physician are truly a thing of the past. You don’t even have to spend big money or leave your home to get a sense of your heart rate during exercise or at rest.
The rise of optical and EKG (electrocardiogram) sensors that can now reliably deliver that information from your wrist, chest, or arm means you can better understand how hard you hit it in that boot camp class and get a window into the most stressful periods of your day.
Updated December 2023: We’ve added the Coros and Viiiiva heart rate monitors, plus the Fitbit Charge 6 tracker.
