How to Choose a Good Heart Rate Monitor

By Natalie van Dasshal


Most heart rate monitors come with a chest strap that wirelessly transmits to the wristwatch. (There are strapless monitors, but I don't think they are as accurate.) A heart rate monitor (HRM) is basically a high-tech gadget that does lots of technical stuff. So how do you pick the right one?

The most accurate heart rate monitors use a chest strap which fits snugly around your chest just below the breast. The transmitter detects the electrical activity of your heart just like an ECG. It relays this to a display, usually worn like a wristwatch, although some use earphones instead, or transmit to apps via Bluetooth. It is important for the strap to maintain contact or you get wild readings.

Exercising without accurately monitoring your intensity is like driving a car without a speedometer. It poses uncertainty (is your intensity level appropriate?), risk (are working too hard for your body to handle?), and health concerns (is your speed improving or hurting your health?).

Basic models display only your heart rate, and perhaps elapsed exercise time. With increasing price you get a variety of useful features such as: Heart rate zone alarm: Set the zone and it alerts you when you are high or low. Timers: Countdown timer, stopwatch, interval timers, clock, alarm. Calories burned. Time in zone, splits. Fitness test. Computer link. Pre-programmed workouts.

Besides features, shop for how easy it is to use. Can you read the numbers easily? Does it have a backlight for use in low light? Are there so many features that you will have to carry the manual to figure out how to use it each time? Are the buttons well labeled and easy to find and push?

Once you have chosen which features you want, it comes down to price. Sales are common and you can find a wide variation in the price of the same model. Shop around and you may be pleased to find your dream monitor for much less than suggested retail price. But the most important thing is to enjoy your workout!
