About Heart Rate Monitoring

The heart rate monitor (HRM) shows your heart rate in BPM (beats per minute) during a workout. To start a workout, you must pair an external HRM device with your watch through the application menu.

The workout starts when the external HRM device (chest belt for instance) starts to send valid data, while being worn.
The workout stops once the external device is removed.

In the activity chart, you can select the HRM workout (heart icon) and see the details. The graph shows the HRM values during the workout, using 4 colors representing 4 different heart rate zones.

The different heart rate zones are displayed using your estimated maximum heart rate in BPM (beats per minute). Your maximum heart rate (HR max) is calculated with the common formula of 220 minus your age.

Red: Maximum Zone

More than 85% of your maximum HR (Heart Rate).
This is the highest intensity zone. It develops maximum performance and speed.
For trained and fit people only.

Orange: Cardio Zone

Between 70% and 85% of your maximum HR (Heart Rate).
This is the medium-to-high intensity zone.
It improves performance and cardio capacity.

Yellow: Fat Burn Zone

Between 50% and 70% of your maximum HR (Heart Rate).
This is the low-to-medium intensity zone.
It improves basic endurance and fat burning. Recommended for longer workouts.

Green: Rest Zone
Under 50% of your maximum HR (Heart Rate).
In this intensity zone, you might be walking and moving but your heart rate is low and you are not exercising.

How to Use the Heart Rate Monitoring Function?

Step 1

Make sure that your watch’s firmware has been updated with the latest version available. Any new watch firmware update is provided by the app and will be indicated by a red dot next to “watch update” in “my watch”. Click and follow the app’s instructions.

Step 2

You will now need to sync your heart rate sensor to your watch. Click on “my heart rate sensor” in the app’s main menu. Bring your sensor closer to your phone and select the detected heart rate device by clicking on its name in the list. Your heart rate monitoring system will be linked to your watch.


Step 3

Start an activity by wearing your heart rate sensor. The measure will start automatically once you start wearing the sensor and select the heart rate function on your watch. It will itself stop upon removal of the device. You should be able to see the live BPM (beats per minute) values on your watch (data accessible by clicking on the AlpinerX’s crown). At the end of your activity, open the app to sync your watch and retrieve your heart rate monitoring session in the activity chart. The heart rate monitoring session is indicated by a small heart icon.

Step 4

Click on the heart icon to display your heart rate monitoring session.
