Getting your pulse taken only once a year at the doctor’s office is a thing of the past. Nowadays, the best heart rate monitors are cheap, comfortable, and ubiquitous. You don’t have to spend a lot of money, or even leave your home, to check your heart rate during exercise or at rest. Even the cheapest fitness tracker boasts a heart rate monitor these days, and sensors are popping up all over the place, with smartwatches, chest straps, arm straps, and even headphones squeezing one in. Not all are built equally. Some are more comfortable to wear, they vary in the metrics they offer, and some are more accurate than others.
Whether you’ve been prompted to keep closer tabs on your ticker due to health concerns or you need a better sense of how hard you’re really pedaling in your Peloton-powered pain cave, these are the heart rate monitors that deliver where it matters. Right now, the best heart rate monitor is the Polar H10 ($85), but the best armband is the Coros heart rate monitor ($79). Be sure to check out the rest of our health and fitness guides, the Best Walking Pads, Best Gravel Running Shoes, and the Best Smart Rings.

H10

Polar
A chest strap remains the most accurate way to track your heart rate for exercise, putting an EKG sensor closest to your heart. The Polar H10 is the standout here. That’s because Polar has replaced the typical loop-and-hook connector found on most monitors with a buckle-style connector to reduce irritation. The company also uses small silicone dots to make sure the strap stays put during high-intensity activities so the HR data is still good.
Comfort aside, it’s the most accurate of the monitors I’ve tested for exercise. There were no glaring drop-outs or underreporting or overreporting during my test runs, indoor cycles, strength training, or interval sessions. Having some built-in memory to store data for a session is useful, and the ANT+ connectivity means you can effortlessly link equipment turbo trainers or swap out the HR stats on your watch for more accurate ones. You can take it for a swim too, and you won’t have to replace the battery for a year, even if you’re wearing it on a regular basis. If you’d to a few bucks, the previous Polar H9 ($70) offers many of the same features for about $30 less.

The Forerunner 970 is Garmin’s most capable runner’s first smartwatch. It takes features from Garmin’s pricier Fenix 8 series and puts them into a more manageable design, while also offering the best heart rate tracking performance. The Forerunner 970 has the latest version of the in-house built Elevate optical sensor, which is the same sensor in the Fenix 8. That setup fuels a rich set of heart rate tracking features, including extremely reliable 24-hour monitoring, powering insightful metrics Training Readiness, or sending out alerts when heart rate is abnormally high or low.
The sensor performance during exercise is where the Forerunner 970 really shines. It more than holds its own against a gold standard chest strap monitor across a range of activities, That includes runs, high intensity indoor bike rides, more explosive home workouts, and also when you’re going all out on race day. Garmin also makes room for an ECG sensor to offer extra health insights on top of the training-focused ones. It’s the optical setup that stands out and helps to justify paying the pretty sizable price to strap it to your wrist.

Tracking heart rate and being in water are two things that typically don’t mix. After planting a great augmented reality display into a pair of swimming goggles, the next challenge for Form was to find a way to measure effort. Enter the Form Smart Swim 2 Pro. After leaning on Polar’s small Verity heart rate sensor, the Smart Swim 2 ($199) and Swim 2 Pro now feature their own optical sensors that sits on one side of the goggles. Positioning that sensor against the temple while making sure hair doesn’t get in the way lets you capture and view real-time heart rate data on the built-in screen, adding to the already solid swim tracking support.
Placement is key, and the goggles will notify you onscreen if they’re not in the optimal spot to generate good quality HR data. Form issued a white paper promising a 97 percent accuracy rate when compared to a heart rate monitor chest strap. It certainly lives up to that promise, from steady-paced swims to more interval-style sessions when I tested them against a chest strap and some of the best-performing smartwatches for tracking heart rate. Upgrading to the Pro version gets you a tougher display, all with the same tracking, training, and coaching features that makes Form’s smart goggles a fine pool and open-water companion.

The Garmin HRM 600 represents the best that Garmin has to offer in heart rate monitoring. If you’re fully locked into the Garmin ecosystem and also happen to have a sports watch the Forerunner 970, then the 600 will feel more worthy of its premium price tag. It comes in two strap sizes, and both are safe to throw into your washing machine. That’s after you’ve removed the sensor module, which usefully includes a pairing and battery indicator light. It carries an 5 ATM waterproof rating so you can slip it underneath a wetsuit while offering strong protection against sweat and rain for those land-based athletes. There’s no battery to remove and replace, as this chargeable monitor can go for months, even with regular training, and uses the same charging cable as most Garmin watches.
It uses an EKG sensor that when put to the test for indoor and outdoor running at a mixture of paces, indoor interval cycling sessions and circuit training and the HRM-600 has been fully up to the task. There’s both Bluetooth and ANT+ connectivity, so you can hook it up to multiple devices at the same time, and it worked perfectly fine paired to non-Garmin devices the Apple Watch. The extra features will appeal most to runners looking to delve deeper into running form, and it can be worn all day if you want it to double up as a fitness tracker. It’s expensive but delivers where it matters and is one of the most feature-packed monitors to strap on.

Coros
Heart rate monitoring armbands are the new kid in town here, and while the Coros Heart Rate isn’t the most feature-packed option, it has the most likable design in terms of everyday comfort. You’re also much less ly to misplace the Coros compared to other armband monitors.
Coros pairs up a not-too-dainty, five-LED light-packing sensor with a Velcro strap that has a welcome stretch to it due to a mix of polyester, nylon, and Spandex. It’s just Bluetooth connectivity here, so no love for ANT+ fans, but this monitor can connect to sports watches, connected gym equipment, and indoor trainers, so don’t sweat it. We’ve found that on runs, indoor rides, and high-intensity workouts, this monitor was typically 1-3 BPM out from a heart rate monitor chest strap—so it’s up to you whether that’s a trade-off between practicality and accuracy that makes sense. It lacks the storage capacity you get with rival HR armbands the Polar Verity Sense ($105), though it does have a useful notification light to let you know when you’ve maxed out on the 38 hours of battery it can muster up on a single charge.

The Whoop MG joined the Whoop 5.0 as a more health-focused alternative to the screen-less band worn by some of the finest athletes on the planet. One of the biggest gains with going for the MG lies with heart rate tracking and access to ECG-style monitoring. That heart health feature comes at an additional cost and does mean opting for the most expensive subscription plan in Whoop’s controversial new tiered service. Only then will you be able to place your thumb and fingers on the electrodes built into the Whoop’s clasp to let the FDA-cleared feature check for signs of atrial fibrillation (AFib) or abnormally high or low heart rate rates.
You still also have photoplethysmography (PPG) sensors to measure heart rate and heart rate variability during the day and night and when exercising. Positioning is key when you want the best data from your workouts. Wearing it on the wrist can cut into an indoor rowing session, but you’ll want to move the sensor into Whoop’s optional bicep strap to make the HR sensor a better fit for high intensity workouts interval running or HIIT. You will need to buy extra accessories to move the MG’s sensors all around the body. There’s few that can match the combination of looks, performance, and software that can help you make better decisions about when to take rest days, have an early night, and now seek out a medical professional.

Powerbeats Pro 2

Despite rumors that Apple would add heart rate tracking to the AirPods, it was the Beats Powerbeats Pro 2 that enjoyed a biometric boost. They’re by no means perfect, but they do perform miles better than any previous heart-rate-tracking earbuds, and could hopefully be a sign of what’s to come for Apple’s white buds.
Apple and Beats do things differently by adding optical PPG sensors in both earbuds that are 1/16th the size of the ones included inside of an Apple Watch. They work with both Android and iOS devices, though it’s surprisingly a more restricted experience with the latter, as they only work with a few select apps. But they offer better heart rate tracking than any other headphones I’ve tested, although they aren’t infallible when you up the intensity of your workout. Add in new active noise cancellation tech, improved overall sound quality, and a slimmer, more refined ear hook design, and these are excellent workout buds that come with the added bonus of solid heart rate monitoring skills.

The Oura Ring 4 remains the smart ring to beat for a host of reasons. It looks great, the companion app is more polished than those of its rivals, and now it’s better equipped to track your heart and make its insights all that more insightful.
Oura has upgraded its optical sensor platform by opening up signal pathways to boost overall tracking accuracy. It’s now also better at monitoring data on different finger shapes and skin tones, and, crucially, when your ring moves around during the day and night. It leads to noticeably more reliable daily and sleep heart rate data. This powers its key Readiness metric, which tells you whether you’re in good shape to take on a stressful day or you should maybe have a chilled one. It also means new features Oura’s Symptom Radar can actually understand when you’re not feeling great.
Recording heart rate during exercise is better too, though it still doesn’t match what you get from the gold standard in monitoring. The improvements are enough, though, to make Oura’s latest ring the best pick if you prefer to wear a heart rate monitor on your finger.

While Apple’s flagship smartwatch may lack the brighter display, bigger battery and extra physical button you get on the Watch Ultra, there’s a strong argument to say that when it comes to tracking your heart, the Series 11 will be a better fit for more people. The Series 11 uses the same third-generation optical features on the Ultra, albeit in a form factor that does sit smaller on the wrist. The more snug fit, combined with Apple’s latest sensor, is capable of doing a pretty impeccable job capturing heart rate in real-time during a spin class as it is keeping tabs on it during the day and night.
You don’t need to be a gym junkie to reap the benefits of that onboard heart rate monitor, either. It can also be used to notify you of potential hypertension. Add in the ECG sensor that can detect atrial fibrillation and make sharing that data to medical professionals a breeze, and you have a smartwatch with serious health tracking prowess. Delve into Apple’s App Store and you’ll find a wealth of apps that want to also put the impressive heart rate sensor to greater use. That’s all nestled inside of a smartwatch that looks great and remains the top pick for iPhone owners.

While it’s tough to know where the future lies for Fitbit’s smartwatches, the Charge 6, its flagship fitness tracker, strengthens its monitoring powers, notably in the heart rate tracking department.
It relies on a similar optical sensor setup to the Charge 5, reliably delivering metrics resting heart rate. It also dips into heart rate variability to estimate when you’re feeling stressed. In the exercise-tracking realm, that sensor performed better for workouts, with Fitbit delivering on that promised 60 percent improved accuracy compared to the Charge 5. That’s across stationary sessions indoor rows and HIIT sessions, and when putting the not-so-fantastic built-in GPS to outdoor use. However, it does still occasionally have its moments throwing up wildly high average and maximum readings. Now you can make the most of that (mostly) reliable tracking and transmit it to connected gym equipment rowers and treadmills. An EKG sensor gives the Charge 6 the power to assess your heart rate rhythm for atrial fibrillation, bringing in a health feature typically reserved for more expensive smartwatches.

FAQS
We tested and recommend all of the heart rate monitors below, which do a pretty impeccable job. But what do all these terms mean?
Heart rate zones: If someone tells you they’ve been doing 80/20 training, they’ve been doing heart rate zone-based workouts. Heart rate zones are an easy way to break down your range of effort during exercise. Zones go from 1 to 5, with 5 indicating working at 90 to 100 percent of your maximum heart rate. Zone 2 represents training at 60 to 70 percent of maximum heart rate and represents light training. 80/20 training is intended to build endurance and means that 80 percent of your runs should be in Zone 2. If your heart rate monitor doesn’t tell you your zone, you can calculate it using Polar’s simple tool.
Maximum heart rate: Some monitors can inform you of your maximum heart rate, which is the number of beats your heart can reach during exercise. This is useful for knowing when you’re training at peak intensity and can be used to create heart rate zones. Factors your age and fitness level can influence what that maximum heart rate will be. You can generate an estimate of your maximum heart rate by simply subtracting your age from 220 and use that at a starting point.
VO2 max: The term VO2 max stands for maximum rate of oxygen your body can consume during exercise; the higher the better. It provides a useful indicator of your ability to sustain intense effort for long periods. Calculating this accurately is done in lab conditions, so heart rate monitors and watches often use their own algorithms to approximate that lab testing.
Heart rate variability: Heart rate variability measures the intervals between heart beats and is measured in milliseconds. High HRV readings are considered better than lower ones, because it means that the body is responding in a resilient way to stress. However, your HRV readings can differ widely from one person to another because they can be influenced by age, fitness level, or even when the measurement was taken.
Resting heart rate: This is the number of times your heart beats in one minute when at rest, which is a simple indicator of your current level of cardiovascular fitness and general well-being. Typically, your heart rate is supposed to sit anywhere from 60 to 100 bpm at rest. A low resting heart rate is associated with athletes, because the heart has been trained to be more efficient. But an uncharacteristically low or high RHR could mean that something is not quite right.
Calories burned: A heart rate monitor looks at your effort based on your heart rate and uses the company’s own algorithms to offer an indicator of how many calories you’ve burned during a workout. Heart rate is one of the strongest, if not the strongest indicators of effort, which means a heart rate monitor is one of the most accurate ways to get this information.
How to Wear a Heart Rate Monitor
Based on those factors above, what kind of information do you need to see? Figuring this out will help you get a heart rate monitor that not only delivers wearability, accuracy, and value, but ensures that you strap it to the ideal part of your body.
Wearing one on the wrist, as part of a smartwatch, may be the most convenient way to track heart rate, though a strap—typically on the chest or, more recently, the upper arm or bicep—can generate more accurate data for activities exercise.
If you want to track heart rate during sleep, make sure you opt for a form factor that isn’t going to feel bulky or become a nuisance for your sleeping companion. If you’re hoping to use it with other fitness equipment or a watch, look for the type of Bluetooth and ANT+ connectivity support to do that with single or multiple devices.
How We Tested
These heart rate monitors are predominantly designed to track your heart during exercise, so that’s how I focused our testing. I used them for a range of indoor and outdoor workouts, including runs, indoor bike rides, rowing, and HIIT-style sessions to see how the monitors fare when it has to track sudden spikes and drops in heart rate.
I also mixed up the duration of those workouts, going from 20 to 30 minute sessions to one hour or longer, to see how the battery performed, particularly for those with rechargeable battery setups. For those that offer a mix of exercise-based and continuous monitoring, I’ve used those monitors alongside other strong-performing HR trackers, to check the accuracy and compare medical-grade heart rate sensors to blood pressure monitors and pulse oximeters that also promise accurate on-the-spot readings.
