Heart-rate estimates calculators
Explore rough age-predicted exercise intensity ranges.
Choose the right calculation
Estimated heart-rate zones are population guides rather than individual safety thresholds. Medication, health conditions and fitness affect responses. Use professional advice when deciding an appropriate exercise programme.
Find a tool for your question
Does an age formula measure my maximum heart rate?
No. It estimates a population average. It does not measure your personal maximum or establish exercise safety.
