Calculate personalized training heart rate zones from your age (and optionally resting heart rate).
Calculate personalized training heart rate zones from your age (and optionally resting heart rate).
Maximum heart rate is estimated as 220 minus your age, and training zones are set as percentages of that maximum. If you provide a resting heart rate, the calculator instead uses the Karvonen method, which factors in your heart rate reserve (the gap between resting and maximum) for a more personalized zone estimate.
