How this is worked out
Maximum heart rate is estimated as 220 − your age, with moderate and vigorous zones shown as percentages of it.
Worked example
- Age 35
220 − 35
185 bpm, with a moderate zone of 93–130 bpm
Assumptions and limits
- The 220 − age formula is a rough population estimate. Individual maximums commonly vary by more than 10 beats either way, so the zones are approximate.
- Medication, particularly beta blockers, lowers heart rate and makes these figures unreliable.
- Not medical advice. Seek advice from a GP before starting vigorous exercise if you have a heart condition or have been inactive.
