How to Choose a Good Heart Rate Monitor

By Natalie van der Brogen


Your heart rate is one of your best, measurable indicators of overall fitness. When you exercise, your heart pushes oxygen-rich blood from your lungs to your muscles (which burn the oxygen like a car burns fuel) and back again. The harder you exercise, the more fuel your muscles demand, and the harder your heart beats. To maximize the benefits of exercise, it is critical to tailor the intensity to what your body is capable of, and your heart rate is your gauge for modifying the intensity level for maximum benefit. As you become more fit, your heart pumps more blood with each beat, your muscles get more fuel, and your heart becomes more efficient, beating at a slower rate. A heart rate monitor allows you to track your heart beat and see whether it's staying at the same level, or decreasing as your training progresses.

While there are many heart rate monitor choices, it's not as overwhelming as it may appear. Not to overly simplify, but the price increases with the number of performance features. Think "basic, better, best." In many cases, you simply do not need tons of features. On the other hand, an heart rate monitor is an investment that lasts years, and we would advise that you select the highest level heart rate monitor that you think you'll need so you're not "penny wise and pound foolish."

A new breed of devices began debuting in 2012 and 2013. Worn as a wristwatch or armband, they use optical sensors on the back of the device to continuously read your pulse through the skin. You get a real-time readout of your heart rate, just as with the chest strap monitors.

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.

If you want to know just steps, distance, and approximate calories burned during the nightly dog walk, a pedometer with its internal pendulum will suit you fine. But if you are looking for more detailed and accurate information about your current level of fitness so you can make progress toward improved fitness, a heart rate monitor is the best tool.

Even though a heart rate monitor can be an excellent way to judge the intensity of your workout, it's still important to pay attention to your body and not rely solely on the monitor for feedback. Rate of Perceived Exertion (RPE) and the "Talk Test" are two other ways to know how hard you're working.
