The Best Heart Rate Monitors for 2023
Heart rate monitors (HRMs) can be immensely beneficial if you know how to use the information they collect. Exercise has dramatically different effects on the body depending on how high you push your heart rate and for how long. Training intelligently means using heart rate data to guide your workouts. Sometimes you might want to keep your heart rate relatively low to burn fat or pace yourself for a longer workout, but other times you might want to push it higher to build stamina. Another reason to own a HRM is to keep an eye on your resting heart rate with a device that can automatically record it for you.
There are many types and styles of monitors available, including those that come in some of our favorite fitness trackers and other health and fitness tech. This article looks at standalone HRMs, though many pair with a fitness tracker or a sports watch for convenience. We cover all the benefits of these separate monitors and list our favorites below. Make sure to read our buying guide at the end as well for some relevant shopping advice.

Buying Guide: The Best Heart Rate Monitors for 2023
How Are Electric and Optical Heart Rate Monitors Different?
First, you need to decide between a classic chest strap that uses an electrical pulse to read your heart rate and something that uses optical technology. Many Fitbit devices, the Apple Watch, and other wrist-based activity trackers rely on the latter, as do sports headphones that record heart rate data via in-ear measurements.

Without getting too technical, chest straps read the small electrical signal your body creates to make your heart contract. Optical technology sends light into the skin and reads the light that reflects back. Based on that information and what we know about how light scatters when it hits blood, these sensors translate the data into a pulse measurement.
Electrical technology tends to be more accurate. Measurements from the arm and wrist are more difficult because those body parts can swing rapidly during activity, thus creating noisier data. In-ear optical HRMs tend to be better than wrist-based ones because the ear doesn’t move nearly as much. The skin of the ear works better for optical readings than the skin on the arm, as well.
Are Heart Rate Monitors Accurate?
Now that you know a little about how different HRMs work and why some are more accurate than others, it’s important to address the issue of how much accuracy matters. There are generally two reasons consumers (i.e., not medical professionals or elite athletes) want to know their heart rate data: to know their resting heart rate and to use heart rate data for exercise and training.
Resting heart rate is easy. You can read it by feeling your pulse with two fingers and counting it. You can also read it using a free app (such as this one from Azumio(Opens in a new window)) and a smartphone camera. It’s easy to read resting heart rate with or without a device, as well as compare data across methods.
More importantly, ask your doctor whether they care if your resting heart rate is, say, 58 versus 60. The answer is probably no. It’s more important to know whether your resting heart rate is within a healthy range. If your heart rate is 80 when it should be closer to 60, that’s a potential concern. The point is that a fine degree of accuracy isn’t important for most consumers.
Similarly, when people use their heart rate for training and exercise, the exact number of beats per minute matters less than the heart rate zone. Many fitness apps and smart home gym machines that pair with HRMs either estimate or calibrate custom heart rate zones for you and show them on a graph with the zones blocked out in different colors. The point, again, is that knowing the exact number of beats per minute isn’t as important as knowing the reading falls within a general range.
There is one more use of heart rate data, and here, accuracy does matter more, but it’s a different kind of accuracy. Heart rate recovery, or how quickly your heart rate decreases after intense activity, is a great measurement of one’s health and fitness. In our testing, chest straps are much more accurate than optical heart monitors for this kind of reading. Optical monitors tend to lag slightly when it comes to detecting rapid heart rate change. Is it enough of a difference to matter to the typical consumer? Probably not. But if you use heart rate seriously for fitness, you might care more about this issue.

Are ANT+ or Bluetooth Heart Rate Monitors Better?
Many HRMs use ANT+, a wireless technology that’s been around since before Bluetooth became popular and is common in a lot of other sports equipment, from bicycle cadence meters to treadmills. Phones don’t typically support ANT+, however. So, when you want to pair an ANT+ device to a phone and app, you often need an adapter. Heart rate monitors that use Bluetooth are much easier to pair directly with your phone. The most versatile trackers support both ANT+ and Bluetooth connectivity.

Should You Choose an Arm Band or a Chest Strap Heart Rate Monitor?
In terms of comfort, chest straps will never get a thumbs up across the board. Chest straps wrap snugly around the chest at the sternum, and if they’re not tight enough, they can slide down or wiggle out of place. Repositioning them while you’re in motion is tough. A bad one can chafe your skin, and they’re poor at providing visual feedback because you can’t see them.
We tend to prefer arm bands over chest straps. They’re much easier to wear, you can adjust them quickly even while you’re in motion, and they don’t cause chafing. They also have LEDs that flash different colors depending on your heart rate zone. That’s the kind of visual feedback you can’t get from a chest strap alone. Usually, with chest straps, you have to rely on a connected tracker to see your heart rate numbers.

Can Heart Rate Monitors Do Anything Else?
Earlier, we mentioned in-ear optical HRMs. They’re neat because they’re built into sports headphones, so you essentially get two devices for the price of one. While these devices cost a lot more than other HRMs, they’re a good value if you’re also in the market for a new pair of wireless sports headphones.
And let’s not forget fitness trackers and smartwatches. Many go beyond basic heart rate monitoring with the ability to take an electrocardiogram (ECG) to assess your heart rhythm for signs of atrial fibrillation (AFib)—an irregular heart rhythm that can lead to serious health problems. That list includes the Fitbit Charge 5, the Garmin Venu 2 Plus, the Apple Watch Series 8, and the Samsung Galaxy Watch 5, among others.
Best Chest Strap Heart-Rate Monitors for 2023
The World Health Organization says adults should do at least 150 minutes of moderate-intensity aerobic exercise per week. To keep track, you need a chest strap heart-rate monitor. Though wearables like smartwatches and smart rings can measure your heart rate easily on the go, the best heart-rate monitors offer some of the most accurate heart-rate readings. Many chest strap heart-rate monitors can also easily pair with your smartwatch, fitness tracker or smartphone.
Heart-rate monitors are helpful for a range of scenarios, including if you’re an athlete training for a race, since they can help you improve your performance or adjust your goals. If you’re the average person who works out for health or fun, tracking your heart rate can keep you in tune with your cardiovascular system, such as monitoring irregular heart rhythms or knowing your heart rate variability, or HRV.
Chest strap heart-rate monitors have a reputation for being uncomfortable to wear during exercise, but we found a few that passed the wear test. Below, you’ll find our picks for the best chest strap heart-rate monitors. We update this list periodically as new models become available.
How we tested chest strap heart-rate monitors
Function during exercise: I tested each one of these heart-rate monitors during strength training and walking workouts to see how well they work for various activities.
Comfort: I rated them based on how comfortable the chest strap felt during my workouts.
Features: I considered the function of various features, like connectivity to other devices or apps, and whether other metrics are captured in addition to heart rate. I also looked at the battery life.
Compared it to a trusted heart-rate monitor: I compared it to my Apple Watch, which captures my heart rate throughout my workouts. While this might not be the best method of testing for accuracy, it’s what I had available to me, and the Apple Watch data is easy to read and consistent.
Factors to consider
- Determine what type of activity you will be doing while wearing a chest strap heart-rate monitor. Most are suitable for a range of cardio activities, from running to cycling, but not all would work for swimming, for example.
- Decide how much you’re willing to spend on a chest strap heart-rate monitor. You can find reliable ones for under $50, but if you want all the bells and whistles you can expect to spend over $150.
- Figure out how important battery life is to you and how often you want to charge or replace it. Some chest strap heart-rate monitor batteries can last over a year, while others can last around 500 hours. This will vary per device and how often you use it.
- Decide if you will be connecting the heart-rate monitor mainly to your smartphone or if you plan on connecting it to other devices. This will influence whether you want it to have ANT Plus or Bluetooth connectivity. Most now come with both, but it’s still important to check.
How to choose a chest strap heart-rate monitor
When it comes to choosing the best heart-rate monitor chest strap for your workout, many of the factors in your buying decision will be based on personal preferences and your workout regimen. Here are a few things to look at while shopping.
Strap width: Before you buy, consider whether you’d be more comfortable with a heart-rate tracker that uses a slim strap or a wider one.
Module size: Some chest straps use tiny modules (the plastic puck-like part) that don’t extend over the edges of the strap. Others, however, use larger monitors to measure your heart rate. Which style you choose to track your workout depends on your comfort preference.
Internal storage: If you don’t like to hold your smartphone during your workout, opt for a heart-rate training monitor that can store your data in its own built-in storage. You can later transfer your heart-rate reading to your phone via your monitor’s companion app.
Metrics: Consider what you want to monitor during your workout. Higher-end models capture real-time data covering everything from run cadence to stride length, as well as things like blood pressure, calorie burn and heart-rate variability to help you reach your fitness goals, while more basic models might track only your heart rate.
Battery: A wearable chest strap monitor can have all kinds of power sources. Some have a rechargeable battery. Others may have super-long battery life, but the battery isn’t user replaceable or rechargeable. A longer battery life is always convenient — no one wants a monitor to peter out during a run — but there are lots of options. Make sure to check the description for battery life before buying a monitor.
Chest strap vs. wrist-worn heart-rate monitors: Chest strap and wrist-worn heart-rate monitors are both used to measure heart rate, but they use different methods to provide readings.
Electrical heart-rate sensors, found most commonly in chest strap heart-rate monitors, can detect electrical currents produced by your heart, somewhat similarly to what is done at the doctor’s office with an ECG. These are considered the most accurate heart-rate readings because the electrical sensor can handle measuring your heart rate even during vigorous activity.
Optical heart-rate sensors use an LED light to track your pulse rate in the arteries as blood pumps through them. Optical heart-rate sensors are found in smartwatches and are useful to read your heart rate while at rest or walking, but are less reliable for high-intensity activity because the readings can be distorted.
ANT Plus vs. Bluetooth: Most wrist-worn heart-rate monitors like the Apple Watch use Bluetooth, which only lets you connect to one device. For example, if you’re recording an outdoor run, you can only connect your Apple Watch to your iPhone.
ANT Plus technology, however, lets you wirelessly connect to multiple devices at once. This is a good option for athletes who are trying to track data from multiple sources. You can find this form of technology on devices like chest strap heart-rate monitors, indoor or outdoor bike computers and some smartwatches.
However, if you’re planning on using a device that uses only ANT Plus technology and want to connect it to your smartphone, know that some Androids have ANT Plus technology capabilities, while iPhones do not. To find out if your device is capable of connecting to your Android, you have to find the ANT Plus Plugins app in the Google Play store and browse its compatible device directory. If you have an iPhone or an Android that does not have the capability to connect to your ANT Plus device, you will need an adapter to add to your phone.
Most people prefer the Bluetooth option because it connects faster and it’s easily found on most devices. The good news is there are many heart-rate monitors that include both ANT Plus and Bluetooth to make the user experience easier.
Heart-rate monitor FAQs
How to use a heart rate monitor and how to choose a heart rate monitor for running
Want to get the right workout? Then you need a heart rate monitor. There are two good reasons to use it: you will be able to train effectively and run at the right pace. The information below will help you find the perfect pace.
Maximum heart rate (HR) training in %
Easy and long runs – 65-75%.
Tempo run – 87-92%.
Spaced Reps – 95-100%.
5000 m – 95-97%.
10,000 m – 92-94%.
Half marathon – 85-88%.
Marathon – 80-85%.
Fern Oliner had been running for over 25 years when she made her first breakthrough while running. It happened at the age of 59, during a difficult half marathon.
“For the first time, I felt like a true runner,” she recalls. “Then I was climbing a mountain, overtaking other people, and I felt completely in control.”
What is her secret? Oliner used a heart rate monitor.
“I was breathing heavily as I climbed up, but my monitor showed that I was fine. So I accelerated,” she says. “If I didn’t have this monitor, I would continue to run at a slow pace, the way I always ran.”
The Oliner experience is a classic example of how runners can benefit from this relatively simple technology.
Once upon a time, gadgets were considered essential companions of professional athletes, but now monitors have become mainstream. Their chest strap signal device now peeks out from under every runner’s jersey, from beginner to marathon runner.
All these people wear heart rate monitors for the same reason: their heart rate is tracked by a sensor that is usually more accurate than the internal perception of their own efforts.
“Even though you get cues from your body, it’s not always a very accurate feedback system,” says George Parrott, Ph.D., running club trainer. “While the monitor is an accurate indicator of your efforts.”
Whether you’re a beginner, intermediate, or advanced runner, a heart rate monitor won’t help you train more efficiently. We’ll show you how to do it. For years, everyone around you has been telling you that the best way to find your maximum heart rate (MHR) is to subtract your age from 220. Sorry about that.
It turns out that this is not the most reliable method, at least not for healthy people. For most of us, the formulas will be more accurate:
(A) MHR \u003d 208 – (0.7 * your age).
(B) MHR = 205 – (0.5 * your age).
A small group of people from a running magazine recently tested these formulas and came up with the following conclusions. Both formulas work equally well for runners under 40. However, formula (B) is more accurate for runners over 40 years of age. We now consider B to be the best formula for predicting maximum heart rate and take it as the standard.
But there is a third option. You can do this test on a track or on a moderately steep hill, which is best for inexperienced runners. And since all the workouts in this article depend on the exact indicator of the MHR, it’s worth doing. To do this, you will need to wear a heart rate monitor.
Here are three basic steps:
1. Make sure you are well rested, hydrated and well warmed up.
2. Run fast for 2-3 minutes. Jog back to the starting point. Repeat runs 2 more times, increasing speed. On the third repetition, imagine that you are running an Olympic race.
3. Check your heart rate during and immediately after the last repetition. The highest number you see is your maximum heart rate (MHR).
Beginners are some of the biggest fans of monitors for two main reasons. First, heart rate tracking ensures you’re working hard enough. Secondly, by setting the maximum heart rate on the monitor, you can avoid overwork.
Beginners should select a target heart rate zone—typically 65% to 75% of MHR—and stay there for most of their workouts. Runners who have not yet developed a sense of speed and effort can learn from a heart rate monitor.
“I like to keep a consistent pace without having to look at my watch all the time,” says Carrie Hardman, 37, who started running two years ago. “Nothing has helped my workouts more than monitoring my heart rate.”
Suggested Workout: This workout is provided by running trainer Roy Benson, a longtime advocate of heart rate training. To perform it, you, first of all, need to determine the MHR. Now take 75% of your MHR and that will be your upper limit. Then calculate 65% of MHR – this will be your lower limit. To calculate these figures, you only need to run for 20 minutes (10 minutes there and then back). Run until you reach your upper heart rate limit, then walk until the number drops to your lower limit. Then start running again up to 75%, and then go again until you hit 65%. Continue doing this for 20 minutes. “After weeks there will be progress, and you will spend more time running than walking because it will take you longer to reach the upper limit,” says Benson. Extend the duration of training as soon as you feel an improvement in physical fitness.
For fun try:
To keep your motivation high, use a heart rate monitor. That’s what Ed Burke, Ph.D., professor of physics advises. Choose your running speed and start running. “Repeat this distance at the same pace a month later, the heart rate should be lower,” he says. Run the same distance after 2 months, 3 months, etc. Record your heart rate in your training log each time so you can track your progress. If you have been running for a year or more and already have a solid run, then you will find a good assistant in the heart rate monitor, especially when you start doing difficult workouts. One of the best ways to use a heart rate monitor is to determine and set the right heart rate for a tempo workout. This will keep you from walking too fast (a common tempo training mistake). Another great way to use it is on long runs where you need to run neither too fast nor too slow for optimal results (aim for 65-75% MHR, depending on your fitness level).
Intermediate and advanced runners are notorious for running too hard on their recovery days, and a heart rate monitor can correct this.
Recommended Workout: This workout scale goes through a range of heart rate zones. After 10 minutes of jogging, run 4 minutes at 70-80% of your MHR, 3 minutes at 80-90%, 2 minutes at 90-95%, and finally 1 minute above 95%. Finish this set with a 10-minute light jog. For less challenging workouts, decrease the amount of time spent in each zone by one minute. To complicate the workout, do 2 or even 3 of these sets.
For fun try:
Even runners who use heart rate monitors all the time during training will gradually leave them at home during races. But heart rate monitors are the perfect tool to learn how to run at the right pace. The heart rate monitor will show if you are running too fast or too slow. Also, if you need to run within the desired zone, the heart rate monitor will allow you to keep pace.
Even the best runners can benefit from heart rate monitors. South African training expert Bobby McGee, who trains some of the world’s top running champions, relies on heart rate monitors to train his athletes.
When star runner Colleen De Riac moved to Boulder Mountains, McGee suggested that she start wearing a heart rate monitor. “She knew how to run easy and how to run hard, but she couldn’t run at a moderate pace,” he says. De Riac, who now wears a monitor for light and intermediate workouts, got used to it very quickly. “I stopped overworking,” she says.
Many advanced runners also use a heart rate monitor to track recovery time during interval training. Instead of waiting a predetermined number of minutes or jogging a certain distance between reps, you can check your heart rate when it drops before starting the next rep. Your recovery must be less than 80% of your MHR.
Suggested Workout: Jog for 10 minutes, then run 3 times at 2.5K (about 90% of your MHR). Rest 3 minutes between each repetition. Record your rep times in your journal. “You’ll see your time decrease with every workout,” says McGee. “You don’t work harder, but at the same time your heart rate gets faster when you run.” By the way, tempo training is a great way to prepare yourself for all race distances, from 5000m to marathon.
For fun try:
An increase in resting heart rate (best measured in the morning, right after you wake up) often indicates that you are overtraining. “Pro runners sleep with their heart rate monitors,” says McGee. – The graph with the results is a very good indicator. That tells me they’re overtrained.” According to McGee, when an athlete has been training hard, they may experience a typical erratic heart rate throughout the night with a lot of variation. With a gradual decrease in load or during rest, the heart rate should be more stable and consistent. If your heart rate is still erratic and may be accelerating, then try to gradually reduce the load or reduce the mileage and intensity during this time.
Or try this: Check your fitness from time to time while running with this game. Warm up well, then pick up the pace until your heart rate reaches 90% of your MHR. Then jog very slowly until your heart rate is back to 70% of your MHR. See how many times you can run from 70% to 90% and back in 10 minutes of running. You can make it harder by raising the upper limit to 95% of your MHR.
