Monitoring your heart rate can help you get to the top of your fitness game faster.

It’s an effective way to gauge your intensity level, so you know when you need to step it up (or when you’re going a little too hard).

If you’re doing a cycling workout on the BODi Bike, tracking your heart rate is easy with the included Polar OH1 Heart Rate Monitor.

Your BODi trainers will guide you through three heart rate zones to help you reach your fitness goals safely and efficiently.

And when you’re not on the bike, no worries — fitness trackers make it easy to monitor your heart rate during any workout.

So what’s the best fitness tracker with heart rate monitor included?

We’ve rounded up six standouts, from the super sporty to the effortlessly chic.

1. Apple Watch, Series 8

The newest and most teched-out version of the Series 8 Apple Watch includes a blood oxygen app, compass, altimeter, and GPS tracking.

It also features an electrocardiogram (ECG) app, which uses built-in electrodes to measure your heart rate and rhythm.

The Apple Watch is water-resistant up to 50 meters.

Are Fitness Trackers Accurate?

If you’re looking for the best fitness tracker with heart rate monitor, you may be wondering about the accuracy of these wearable devices.

Studies have compared the accuracy of a few different wearable fitness trackers — including the Polar OH1 and the Apple Watch 3 and Fitbit Charge 2 — to the results from an ECG device when monitoring heart rate during physical activity.

In the studies, researchers found the accuracy of the trackers to be acceptable when compared to the results from an ECG.

Of course, accuracy may vary depending on which tracker you choose — but wearing a heart rate monitor can help you gauge your intensity throughout a workout.
