How to Pick the Right 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.

Consider the ease of use when making your choice. Most monitors come with a watch and chest strap. That makes it very easy to monitor your stats during your workout. However, there are a few that don't require a chest strap, instead detecting your pulse by placing one or two fingers on sensor buttons. These cannot give you a constant reading of your pulse and are not as accurate as the chest strap models. In addition, it can be difficult to stop your workout, put your fingers on the sensors, wait for a reading, and then resume the workout.

Learn about your heart as a gauge of your fitness, use a heart rate monitor to improve your health without risking wasted time or injury, and get outside to play!
