Best Heart Rate Monitors in 2021 – Suggested By Professionals!

Are you into exercise? Did you know that the most important measurement you need while exercising is your heart rate? It’s true, because for the most benefit possible your heart should be beating in a range between 90 and 160 beats per minute while you exercise, depending upon your age.

Best Heart Rate Monitors

To make sure you’re getting the most out of your physical activity, you need to know your heart rate, so to measure that you need a heart rate monitor. There are plenty of heart rate monitors for sale, but which ones are the best?

After hours of research, I have identified several of the best ones, and also what you should look for when shopping for your new heart rate monitor. If you’re in the market for a new heart rate monitor, read on because there’s plenty of information here that will help you with your new purchase. Let’s begin:

Best Heart Rate Monitors : Things to Consider

There are five main considerations you should take into account when shopping for your new heart rate monitor. Here they are in no particular order:


Heart rate monitors are typically worn in one of two places. They either mount on your wrist as a watch, or they use a chest strap to monitor your heartbeat.

While wrist mounted monitors tend to be a little inaccurate, they are definitely more comfortable and convenient to use. If you want the most accurate heart rate data, you’ll need the chest strap, but they can be a pain to use sometimes. Figure out which style best suits your needs.


We know you want to keep track of your heart rate data, but what other data does the device keep track of? Common data from fitness devices include steps, distance, calories burned, sleep patterns, and goal progress.

Identify which data is important to you, and make sure your new heart rate monitor tracks it. Some people like as much information as they can get, while others like to keep it simple. Know yourself and get a monitor that matches your needs.


Most modern fitness devices have at least a minimum amount of connectivity. They are usually linked to your smartphone or tablet via Bluetooth to transmit and share your exercise data, and they can also be used as an extension of your device.

For example, texts, caller ID, and emails can sometimes be reviewed on your device while you’re exercising. Look for an advanced app for your smartphone that allows you to sync your device to keep track of your progress towards your fitness goals. Connectivity is an important feature to have with any new heart rate monitor.

Customer Reviews

I found out during my research that products can look really great on the internet, but when you get them it’s a different story. That’s where great shopping sites like Amazon can be a great help.

Below the products are usually extensive customer review sections where you can read what real people who have purchased and used the product say about it.

You can quickly gauge whether the reviews are generally positive or negative, which tells you a lot about it. Read some of the top positive reviews, and then review the most negative ones.

You can tell if people had real issues with quality, performance, or customer service. Let the experiences of others help guide your decision.


All buying decisions are influenced at least to some degree by price. My advice is to set a budget before you look at any products.

Figure out what you are willing to spend at the maximum, and stick to it. Setting a reasonable purchase price amount ahead of time can help stop you from making an expensive impulse purchase, plus it helps you weed out the products that are out of your price range very quickly.

5 Best Heart Rate Monitors in 2021

1. Fitbit Surge Fitness Superwatch

Fitbit is one of the most popular names in fitness devices today, and their Surge Fitness Superwatch is a fantastic product that provides heart rate data from your wrist. Here are a few of its best features:

The Fitbit Surge doesn’t just count your steps. This fitness watch is a full on GPS tracker. At the end of your hike, walk, ride, or run, you can see the distance covered, your speed, elevation changes, and review your route.


You can also share the GPS data with others to start a little friendly challenge for motivation! Using GPS technology, your data will be accurate to within six inches.

Heart Rate

Your current pulse rate is displayed in easy to read large numbers next to a heart, and the simplified heart rate zones let you know when you’re in the best range for you. Getting heart rate data from your wrist is the most comfortable way available.


After each workout or at the end of the day, you can view your accomplishments with convenient summaries. The Surge will keep track of your steps taken, distance you’ve covered, how many calories you burned, how many floors you climbed, and how many minutes you were active throughout the day. The Surge is much more than a heart rate monitor, it’s a complete fitness computer.
