How it works

Maximum heart rate uses the age-based estimate 220 − age. When you supply a resting rate, the zones use the Karvonen heart-rate-reserve method, which is more personal.

Frequently asked questions

Which zone burns the most fat?

Zone 2 burns the highest share of fat per calorie, but higher zones burn more total calories per minute.

Is 220 minus age accurate?

It is a rough average with a wide spread. A lab test or a hard field test gives a much better figure.
