Based on your training preference, you can select three different heart rate zone types on your COROS app.
- Max Heart Rate Zone
- Heart Rate Reserve Zone
- Lactate Threshold Zone
You can view the time spent in each zone on the COROS app and on the watch for each workout. Usually, the time you spend in all 5 heart rate zones is close to the workout time of med- to high-intensity activity. However, you may notice only a small amount of time is recorded in the heart rate zones for low-intensity workouts.
For instance, I recorded my 90-min playtime with my cat at home. The heart rate zones only recorded less than 3 minutes. The reason is that the majority of my heart rate readings are below the Aerobic Endurance zone (136 - 155).
Here's another example of a one-hour GPS Cardio workout. The heart rate zones only missed 10 minutes at the beginning and the end of the workout due to lower readings.
If you would like to customize the heart rate zones, please follow the steps below.
- On the Profile page of the COROS app, tap on your profile image.
