Calculate your maximum heart rate, target heart rate zones, and heart rate reserve for optimal training.
Maximum Heart Rate: bpm
Target Heart Rate Zones:
  • Moderate (50–60%): bpm
  • Fat Burn (60–70%): bpm
  • Cardio (70–85%): bpm
  • Peak (85–95%): bpm

About Heart Rate Zones

Heart rate zones help you train safely and efficiently. Knowing your max and target heart rates allows you to tailor workouts for fat burn, endurance, or peak performance.

How It Works

Maximum heart rate is calculated as 220 minus your age. Target zones are percentages of max HR. If you provide resting heart rate, the Karvonen formula calculates heart rate reserve for precise training.

Advice

Always warm up before high-intensity exercise. Use zones to avoid overtraining. Consult a professional if you have cardiovascular concerns.

FAQs

Is this exact? No, these are estimations.
What if I don’t know my resting HR? You can still use target zones based on max HR.
How often should I calculate? Recalculate if your fitness level or age changes significantly.
