Heart Rate Zones Calculator

Calculate your personalized heart rate training zones for optimal cardio performance, fat burning, and endurance training based on your age and resting heart rate.

Calculate Your Heart Rate Zones

Measure first thing in the morning before getting out of bed

How to Use Your Zones

Zone 2 (60-70%): Fat Burning

Perfect for steady-state cardio. Train 60+ minutes, 3-5x weekly for optimal fat metabolism.

Zone 3 (70-80%): Endurance

Build aerobic base and improve lactate threshold. Great for longer tempo sessions.

Zone 4-5 (80-100%): Performance

High-intensity intervals and sprint work. Use sparingly (1-2x weekly) to avoid overtraining.

Monitoring Your Training

Heart Rate Monitors

Use chest straps or wrist-based monitors for accurate readings during exercise.

Rate of Perceived Exertion (RPE)

Scale of 1-10 based on how hard you feel you're working. Should correlate with zones.

Training Load Balance

Mix easy, moderate, and hard sessions. Include recovery weeks every 4-6 weeks.

Important Note

These calculations provide general guidelines based on population averages. Individual responses vary based on fitness level, medications, and health conditions. Consult a healthcare provider before starting new exercise programs.

Understanding Heart Rate Training

Why Train in Zones?

  • • Optimizes specific energy systems
  • • Prevents overtraining and injury
  • • Maximizes training efficiency
  • • Allows for progressive overload

Factors Affecting HR

  • • Fitness level and training status
  • • Age and genetics
  • • Environmental conditions
  • • Stress and recovery status
