Frequently asked questions
What does this heart rate calculator do?
Estimate heart-rate training zones from age and resting heart rate.
How do I use this heart rate calculator?
Enter age, resting heart rate, and intensity.
What does the result mean?
Zones describe relative exercise effort.
What should I check before relying on it?
Medication and health conditions can affect heart rate.
How is maximum heart rate estimated?
This uses the common formula 220 minus age, which is a population-average estimate — actual maximum heart rate varies by individual and can differ meaningfully from this formula.
What is heart-rate reserve used for?
It's the gap between resting and maximum heart rate, used to calculate more personalized training zones than percentages of maximum heart rate alone, since it accounts for your individual resting rate.
