Heart Rate Zone Calculator
Enter your age to calculate estimated max heart rate and training zones for different workout intensities.
Estimated max heart rate: 190 bpm
| Zone | BPM range |
|---|---|
| Zone 1 — Very light | 95 - 114 |
| Zone 2 — Light (fat burn) | 114 - 133 |
| Zone 3 — Moderate (aerobic) | 133 - 152 |
| Zone 4 — Hard (anaerobic) | 152 - 171 |
| Zone 5 — Maximum | 171 - 190 |
Uses the common 220-age estimate — individual max heart rate can vary meaningfully, so a lab or field test gives a more precise number.
