Heart Rate Zone Calculator

The most common formula is 220 minus your age. A 30-year-old would have an estimated max heart rate of 190 BPM. This is an estimate that varies by individual.

Zone 1 (50-60%) is recovery, Zone 2 (60-70%) is fat burning, Zone 3 (70-80%) is aerobic cardio, Zone 4 (80-90%) is anaerobic training, and Zone 5 (90-100%) is maximum effort.

Zone 2 (60-70% of max HR) is the 'fat burning zone' as your body uses fat as its primary fuel. However, higher intensity zones burn more total calories in less time.
