Calculate Your Target Heart Rate Zones by Age & Fitness Level

What is Target Heart Rate?

Your Target Heart Rate (THR) is the range your heart should beat during exercise for safe and effective cardiovascular training. It helps optimize fat burning, endurance, and heart health.

How is Target Heart Rate Calculated?

We use the Karvonen Formula for accuracy:

Target HR = [(Max HR − Resting HR) × %Intensity] + Resting HR

  • Max HR = 220 − Age
  • Heart Rate Reserve (HRR) = Max HR − Resting HR

Heart Rate Training Zones Explained

  • Very Light (50–60%): Warm-up and recovery zone
  • Light (60–70%): Fat-burning and endurance
  • Moderate (70–80%): Cardio fitness and aerobic training
  • Hard (80–90%): Performance and power building
  • Very Hard (90–100%): Maximum effort and sprint training

Benefits of Knowing Your Heart Rate Zones

  • ⚡ Train efficiently and safely
  • 💪 Improve fat loss and endurance
  • ❤️ Strengthen your cardiovascular system
  • 📊 Tailor intensity for better fitness outcomes
