How to Use Your Heart Rate Zones

Heart rate zones help you optimize your workouts by targeting specific training intensities. Use the calculated zones to guide your exercise intensity based on your goals:

  • Zone 1 (Recovery): Warm-up, cool-down, active recovery
  • Zone 2 (Endurance): Improve aerobic capacity and fat burning
  • Zone 3 (Tempo): Increase aerobic endurance and efficiency
  • Zone 4 (Threshold): Improve lactate threshold and speed
  • Zone 5 (Maximum): Enhance anaerobic performance and power

For best results, vary your training across different zones throughout the week based on your fitness goals.


The Heart Rate Zone Calculator is a simple tool that helps you figure out how hard you should exercise based on your age and heart rate. Knowing your heart rate zones lets you train smarter — whether you want to burn fat, improve endurance, or increase performance.

What are Heart Rate Zones?

Heart rate zones are different intensity levels of your heart rate during a workout. Each zone serves a different purpose. They are usually based on a percentage of your maximum heart rate.

How to Calculate Maximum Heart Rate

The most common formula to estimate your maximum heart rate (MHR) is:

MHR = 220 − age

This number is then used to find your zones by multiplying it by certain percentages.

Heart Rate Zones Explained

  • Zone 1 (50–60% of MHR): Light activity, good for warm-up and recovery
  • Zone 2 (60–70% of MHR): Fat burning zone, ideal for long cardio workouts
  • Zone 3 (70–80% of MHR): Improves aerobic fitness and endurance
  • Zone 4 (80–90% of MHR): Hard training zone, builds speed and strength
  • Zone 5 (90–100% of MHR): Maximum effort, for short bursts of intense activity
