It measures the electric pulses your heart makes, thus giving precise results.

Per the manufacturer, this chest strap offers consistently accurate measurements. In addition, it won’t lose your heart rate at any point, no matter how much you move around.

Besides your heart rate, the user-friendly app displays the workout duration, burned calories, distance, and average and maximum heartbeat.

If you’ve never used a chest strap before, you may be worried about how comfortable it is. However, most users say they got used to the strap after only a few minutes and forgot they had it on. The band is made of premium materials and is very stretchy, so it won’t constrict your breathing, get in the way of sports bras, or be noticeable under shirts.

The Polar H10 Heart Rate Monitor is compatible with GoPro. You can pair the devices and overlay your heart rate on the videos you record.

Polar FT1 Heart Rate Monitor

If you want to keep track of your heart rate without additional bells and whistles, the Polar FT1 Heart Rate Monitor is your device. This set consists of two key components. The first is a chest strap that measures your heart rate, and the second is a monitor watch that displays your heart rate data.

The monitor shows real-time heart rate, thus allowing you to stay on top of your exercise session and adjust it if necessary. For example, you can use the watch to set a minimum and maximum heart rate for your workouts. If you fall below the minimum or go above the maximum, the monitor will beep until you get back in the zone.

Both the watch and the chest strap use batteries that aren’t rechargeable and will require a replacement. While some users may find this annoying, others like it because they don’t have to worry about charging the devices regularly.

The chest strap is adjustable, comfortable, and stretchy, so it won’t disrupt your workout. It uses an electrocardiogram (ECG) that provides precise heart rate readings.

The watch has only one button, so setting it up is very easy. Although most users like the one-button functionality, others feel it would be simpler to have additional controls.

Buyer’s Guide

If this is your first time buying a heart rate monitor, you may find the process overwhelming, mainly because many options are on the market. Here are some crucial factors you should consider when purchasing a heart rate monitor.


Heart rate monitors are designed to provide insight into how your heart behaves while working out. Most modern monitors will keep track of your resting heart rate as well. Resting heart rate — or pulse — represents the number of heartbeats per minute while you’re resting.

Many users are interested in other measurements fitness trackers can provide. Steps, distance traveled, floors climbed, calories burned, active minutes, and sleep quality are only some of the data modern fitness trackers can provide.

Keep in mind that not all fitness trackers have the same options. Which one you choose depends on what you want from a tracker and your budget. Trackers with fewer features tend to be more affordable.

Strap Width

Strap width is another factor you should consider when purchasing a heart rate monitor. Although strap width doesn’t affect a monitor’s functionality, it’s crucial for your comfort. Depending on your personal preferences, you can choose between thinner or wider straps.


Heart rate monitors exist in the form of wrist-based monitors and chest straps. Both have their pros and cons, and it’s essential to establish your priorities before opting for one. For example, chest straps provide more accurate readings because they feature advanced sensors. However, they aren’t as convenient as wrist-based monitors.

Most wrist-based monitors are easy to use and offer a variety of other valuable features for tracking fitness and health. But they aren’t as accurate as chest straps for high-intensity workouts.


Many people don’t like to hold their phones close while working out because they distract them. If you’re one of them, you need a heart rate monitor to store your workout data in its built-in memory. Then, after completing the workout, you can transfer the data to your smartphone and analyze the results.


Heart rate monitors have different power sources. Some are powered by batteries that require charging every few days, while others have extra-durable batteries that can’t be recharged or replaced by users.

It’s impossible to say one is better than the other because it all comes down to your preferences. However, to avoid unpleasant surprises, it’s essential to carefully check a monitor’s battery information before buying it.


Why Should I Monitor Heart Rate and Not Just Steps?

Many people have set step goals that keep them motivated to stay active. While this can be an excellent basis for a more active lifestyle, counting steps isn’t enough because the number doesn’t show the intensity.

For example, walking 10,000 steps on a treadmill and walking 10,000 uphill don’t have the same intensity. We get insight into how intense our workout is by monitoring our heart rate. Plus, we can track how our resting and recovery heart rates change as our physical condition improves.

Are Electric or Optical Monitors More Accurate?

Because they measure electric signals in our blood, electric heart rate monitors tend to be more accurate than optical models that use green LED light. These days, many smartwatches feature both the ECG and green light technology, so you can be confident you’re getting accurate readings.

Remember that neither electric nor optical heart rate monitors will provide accurate readings if they aren’t positioned correctly. If you’re wearing a chest strap, you need to ensure it’s tight enough. The same goes for smartwatches. If they’re loose, the heart rate measurements won’t be correct.

How Does a Heart Rate Monitor Work?

Electric heart monitors measure your heart’s electrical signals using an electrocardiogram (ECG). Optical heart monitors use photoplethysmography (PPG) to determine your heart rate. This technology is based on shining light into the skin and measuring the changes in blood flow that determine your heart rate.

Regardless of the heart rate monitor type you choose, it’s crucial to remember to position it correctly. If the monitor is too loose, it won’t be able to determine the heart rate accurately, and you’ll get inaccurate results.

What Are the Benefits of Using a Heart Rate Monitor?

Using a heart rate monitor has numerous benefits. First, they provide essential information about your workouts. Besides informing you how fast your heart is beating, they allow you to learn more about how many calories you’re burning. You can use this valuable info to adjust your workout intensity.

If you’ve just started working out, it can be hard to determine when your body’s had enough. A heart rate monitor can help you learn when to stop or take a break. The monitor will warn you if your heart rate is too high and prevent overstraining your body. Some models will even suggest breathing exercises for controlling your heart rate.

As you become more fit, your resting and recovery rates change. A heart rate monitor enables you to track these changes and monitor your overall progress over time.

It acts as your personal coach and ensures you don’t slack or overtrain. It helps you achieve your fitness goals and create a healthy workout routine.

What Are the Different Types of Heart Rate Monitors?

Heart rate monitors are divided into two groups, depending on how they operate. The first group is monitors with a built-in electric sensor (ECG) that measures electric signals in our blood. These signals help the monitors determine the timing and strength of our heart rate.

The second group is optical monitors that use green LED lights. The lights reflect on the blood and measure how fast the blood flows through your veins.

Final Verdict

As you can see, heart rate monitors come in various shapes and additional features. If you need only the monitor without extra options, we recommend the Polar H10 Heart Rate Monitor. The chest strap monitor is easy to use, accurate, and comfortable. It may take some time to get used to it, but you’ll forget you’re wearing it once you do.

If you want a fitness tracker with a built-in heart rate monitor and a wide range of other options, we recommend the Fitbit Charge 3. This stylish device has everything you need to keep track of your workouts and use the data to improve your fitness.

We hope this article helped you find the best heart rate monitor and that you’re now enjoying your workouts even more.
