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. In addition, each Apple Watch has five heart rate zones that show you the intensity of your workout by measuring your heart rate at different stages of your workout.

The heart rate zone should not be confused with the heart rate, as the latter is the number of times the heart beats per minute.

Note. Heart rate zones will be calculated based on the information you provide in the Health app on iPhone.

Why Use Heart Rate Zones?

The heart rate zone is a plus as it would be difficult to constantly monitor the heart rate sensor and calculate your heart rate during a cardio workout. By integrating heart rate zones into watchOS 9, Apple has completely simplified the calculation and calculation process and allowed you to focus solely on exercise.

It’s important to keep in mind that you may not find numbers as similar to those shown here, and the reason for this is that my health data and your health data will not match. For a person born in 1998 who weighs 80 kg and is 170 cm tall, Apple classifies five heart rate zones as follows:

• Zone 1: Heart rate below 141 bpm or 60% of maximum heart rate.
• Zone 2: Heart rate is in the range of 142-153 beats per minute or 60-70% of the maximum heart rate.
• Zone 3: Heart rate is in the range of 154-165 beats per minute or 70-80% of the maximum heart rate.
• Zone 4: Heart rate is in the range of 167-178 beats per minute or 80-90% of the maximum heart rate.
• Zone 5: Heart rate above 179 bpm or 90% of maximum heart rate.

Maximum heart rate: 220 – age

Note. Here HR refers to the heart rate.
