About Target Heart Rate Calculator

Our Target Heart Rate Calculator helps you determine your optimal heart rate zones for different types of cardio workouts.

Heart Rate Zones

  • Recovery Zone (50-60%): Light activity for recovery and warm-up
  • Fat Burn Zone (60-70%): Moderate intensity for fat burning and endurance
  • Aerobic Zone (70-80%): Moderate to high intensity for cardiovascular fitness
  • Anaerobic Zone (80-90%): High intensity for performance improvement
  • Maximum Zone (90-100%): Maximum effort for short intervals

How to Calculate

The calculator uses the Karvonen Formula to determine your target heart rate zones:

  • Maximum Heart Rate = 220 - Age
  • Heart Rate Reserve = Maximum Heart Rate - Resting Heart Rate
  • Target Heart Rate = (Heart Rate Reserve × Intensity) + Resting Heart Rate

Important Notes

  • Always consult with a healthcare provider before starting a new exercise program
  • Monitor your heart rate during exercise using a heart rate monitor
  • Stay hydrated and listen to your body
  • Progress gradually to avoid injury
  • Consider your fitness level and health conditions
