Three ways to use Polar A370 as a heart rate sensor

October 4, 2017

Wrist-based heart rate monitoring is one of the simplest ways to track your heart rate: all you need to do is tighten the wristband and you’re ready. Our Polar A370 fitness tracker measures your heart rate from your wrist and displays it during your workouts, but did you know that you can also turn your Polar A370 into a heart rate sensor and broadcast your heart rate to other devices via Bluetooth? In this post we introduce three ways to make the most of this nifty little feature.

1. For app lovers

Some of us are really into phones. And apps. Some of us bring our phones with us everywhere. Some of even track all workouts with apps. If one of the world’s many fitness apps (like Polar Beat, our free training app available for both iOS and Android) has a special place in your heart, you can use Polar A370 to broadcast your heart rate to your phone and the app during your workouts. Many apps offer features that are based on heart rate measurement, so heart rate tracking with Polar A370 can help you make the most of your app.

By the way, did you know you can also link your Polar Flow account to some of the most popular fitness apps, such as MyFitnessPal, and get all your training and activity data directly to into the app?

2. For bike commuters

Many of us prefer the freedom of riding a bike past the morning rush hour traffic jams. If you’re a keen cyclist and a happy owner of a Polar M460 GPS cycling computer, Polar A370 can make your commutes just a little simpler. You can use the heart rate sensor mode on Polar A370 to track your heart rate from your wrist and broadcast it to your Polar M460. This way, you can track your heart rate during your commute while optimizing the amount of gear you need for the day. With Polar A370, you get a heart rate sensor for the commute and an activity tracker, calorie counter and an activity reminder for your day at the office.

If you have a bike mount for your phone instead of a bike computer, this solution also works with Polar Beat. Using an app to display your heart rate when you cycle can even promote safety: when you don’t need to check your heart rate from your wrist, you can keep your hands to the bars and your eyes to the front and focus on the commotion around you.

3. For gym and group fitness freaks

Many gyms have workout equipment that connect to Bluetooth devices. If your gym has a Bluetooth-compatible treadmill, for example, you can broadcast your heart rate to the treadmill from Polar A370.

For some, group fitness such as LES MILLS classes is the most motivating form of exercise. One of the best things about group fitness is the support you get from everyone around you, and we at Polar came up with a great way to share the fun: Polar Club. If your gym isn’t using Polar Club yet, here are the basics: Polar Club is a group fitness app that displays the names, heart rates and calories burned for everyone in the class on a screen.

Fitness clubs lend heart rate sensors for Polar Club classes to those who don’t have one, but if you have a Polar A370, you can use it to broadcast your heart rate data to the screen. Read this to learn how it works.
