Heart rate zones calculator
Calculate maximum heart rate and training zones by age and selected formula.
How are heart rate zones calculated?
The simple maximum heart rate formula is 220 minus age. Zones are calculated as percentages of this approximate maximum heart rate.
If you enter resting heart rate and choose the Karvonen method, the calculator uses heart rate reserve: maximum heart rate minus resting heart rate.
The result is approximate. If you have heart disease, high blood pressure, medicines or unusual symptoms during exercise, consult a doctor.
