Heart Rate Zone Calculator

Your heart rate zones, explained

This calculator estimates your maximum heart rate from your age (the simple 220-minus-age formula) and splits it into five training zones — from a gentle warm-up to peak effort. Working out in the right zone helps you train smarter, whether you're building endurance or just staying active. Maximum heart rate varies between people, so treat it as a guide.
