From improving your fitness and performance to managing your heart health and stress levels, there are plenty of beneficial reasons to use a heart rate monitor. The two main types of heart rate monitors are chest straps and wristbands or watches.
When selecting a heart rate monitor, it’s important to consider how and why you’ll be using it. A wristband or watch is generally more comfortable on long runs or rides while chest straps provide more precise readings for heart rate training. Another feature to consider is ease of use. If the device is complicated, it’s not helpful. We reviewed the heart rate monitors in our roundup for these features as well as durability, comfort, and connectivity.

What to Look for in a Heart Rate Monitor
Accuracy
If you’re monitoring your heart rate to make sure you’re training in a specific range, then you’ll want a device that’s reliable and precise. Generally, chest straps that use electrocardiography are known to be the most accurate. With this method, the chest strap’s electrode pad picks up electrical signals given off with each heartbeat, which allows for continuous heart-rate readings.
Final Verdict
For accuracy, comfort, and performance, it’s tough to beat the high-quality Polar H10 Heart Rate Monitor. The extra-long battery life, secure fit, reliable results, and Bluetooth and ANT+ compatibility make it a solid choice for runners, indoor and outdoor cyclists, and other fitness enthusiasts.
If you prefer a wristband monitor for the convenience of viewing your heart rate and other fitness stats at a glance, the Fitbit Versa 2 Smartwatch is another reliable, versatile pick. It’s easy to operate, comfortable, and can be used to track a wide variety of activities and health metrics.
Optical heart rate monitors, which include wristband and armband devices, use small LED lights to track your pulse. Although that method can also produce reliable readings, the accuracy depends on a secure, tight fit, and outliers in readings may be present.
Comfort
Even the most comfortable chest straps can start to feel constricting and may lead to chafing issues during seriously long rides or runs. Armbands and wristbands are usually a better fit for long training sessions, especially in the warm weather.
Connectivity
Analyzing the data collected from your heart rate monitor can help you monitor your progress, fine-tune your workouts, and provide useful information to a coach or healthcare professional. If you want to view your stats over time, look for a model that can be synced to an app or have its data downloaded to a computer.
Some heart rate monitors use ANT+ technology, a wireless system that’s used with exercise machines such as Peloton. Others offer Bluetooth technology, which for some, may be easier to use and can connect the device directly to your phone.
Ease of use and compatibility
If a device is too difficult to use, then you won’t be able to take advantage of all its benefits and features. “Make sure the device meets your needs and is compatible with the exercise equipment you’re using and technology used at certain exercise facilities,” says Chris Gagliardi, a certified personal trainer and Scientific Education Content Manager for the American Council on Exercise.

Frequently Asked Questions
- How do heart rate monitors work?
- Chest strap monitors typically use electrocardiography to measure the electrical activity of the heart, while armband and watch-style monitors use small LED lights to measure blood flow through the skin in a process called photoplethysmography. With both types of monitoring, the collected data is then transferred to a receiver, such as a watch or an app, so you can view your heart rate in real-time.
- How to read heart rate monitor results
- Many people use a heart rate monitor when exercising to hit their target heart rate zone and get the most out of their workouts. Some basic monitors just relay your heart rate, so it’s up to you to know your target zone based on your age and fitness level and to determine whether you’re exerting the right amount of effort. Some more high-tech devices send notifications when you reach your target zone and if you drop below or go above it.
- What’s the most accurate type of heart rate monitor?
- Chest strap monitors detect electrical signals emitted from each heartbeat, so they usually produce the most accurate results. They still need to maintain secure, wet contact with your skin for good reading and will be less effective if they’re slipping and sliding. Optical heart rate sensors, which are usually worn on your wrist or arm, can be reliable but their accuracy may be reduced if the fit is not tight and light leaks in from the sides.
- What are the different styles of heart rate monitors?
- The most common styles of heart rate monitors are chest straps, armbands, and wristbands. While chest straps are typically more accurate, armbands and wristbands are usually more comfortable and convenient. Newer products, such as earbud monitors or fitness rings, are less cumbersome but tend to be pricier and less reliable than other styles.
