Monitoring your heart rate during exercise is a powerful way to gauge your effort levels and ensure you're training at the right intensity for your goals. 

What is a heart rate zone?

Heart rate zones represent different percentages of your maximum heart rate. Different heart rate zones represent different levels of intensity.

While exercising, it’s a good idea to spend time in a variety of heart rate zones depending on your goals. For example, here’s how you may use zones for certain types of exercises:

  • Zone 1 is the target zone for warm-ups and recovery. This zone should feel easy, like you can go on for hours.
  • Zone 2 is the target range for base-level aerobic activities. This zone should still feel comfortable and easy.
  • Zone 3 is the target heartbeat range for aerobic endurance activities. In this zone, you should be starting to breathe deeper and feel a moderate effort.
  • Zone 4 is the target range for anaerobic activities. You’ll feel fatigue in your muscles in this zone and breathe heavily.
  • Zone 5 is ideal for short burst speed training. This zone should feel exhausting for breathing and muscles.

How to calculate your heart rate:

The percentage of maximum heart rate method involves calculating heart rate zones based on a percentage of your maximum heart rate, which can be estimated by subtracting your age from 220. 

For example, a 40-year-old male would have an estimated maximum heart rate of 180 bpm (calculated as 220 bpm – 40 years of age = 180 bpm).

To calculate the heart rate range for each zone, simply multiply the maximum heart rate by the corresponding percentage limit for each zone.

Different heart rate zones are recommended for different types of exercises and goals. Heart rate zone training can be a great tool for creating an intentional cardio training program and can help you to measure your progress over time.

Heart rate zone training can help you to achieve your fitness goals by providing a framework for monitoring and adjusting exercise intensity. By understanding heart rate zones and how they correspond to different levels of exertion, you can plan your workouts to target specific heart rate zones and achieve specific fitness benefits.
