Apple made significant advancements in the fitness space with watchOS 9 and iOS 16. Heart Rate Zone tracking is one of the most exciting features added to the arsenal of the Apple Watch recently. Confused about Heart Rate Zones? Don’t worry. In this article, I’ll explain what heart rate zones are and how you can use Heart Rate Zone tracking in watchOS 9.

What are Heart Rate Zones?
Apple explains Heart Rate Zones as a percentage of your maximum heart rate; it is automatically calculated and personalized using your health data. Also, each Apple Watch has five heart rate zones that show your training intensity by measuring your heart rate at different stages of a workout.
Heart Rate Zone should not be confused with heart rate as the latter is the number of times a heart beats in one minute.
Note: Heart Rate Zones will be calculated based on the information you’ve provided in the Health app on your iPhone.
Why use Heart Rate Zones?
Heart Rate Zone is a plus as it would be difficult to constantly monitor the heart rate machine and calculate heart rate while doing a cardio-based workout. By integrating Heart Rate Zones in watchOS 9, Apple has completely streamlined the process of calculations and computations and allowed you to focus solely on your exercise.
It’s important to keep in mind that you might not find numbers as similar as those given here, and the reason behind this is that my health data and your health data won’t match. For someone born in 1998, whose weight is 80 kg and height is 170 cm, Apple categorizes five Heart Rate Zones as follows:
- Zone 1: HR is below 141 bpm or 60% of Max HR
- Zone 2: HR is between 142-153 bpm or 60-70% of Max HR
- Zone 3: HR is between 154-165 bpm or 70-80% of Max HR
- Zone 4: HR is between 167-178 bpm or 80-90% of Max HR
- Zone 5: HR is above 179 bpm or 90% of Max HR
Max Heart Rate: 220 – age
Note: Here, HR refers to heart rate.
