Health Calculators
Estimate broad adult exercise-intensity heart-rate ranges by age with visible formulas and prominent limits on what the result can establish.
The heart-rate figures are population-level estimates, not personalised safe limits, a diagnosis or an exercise prescription. Medicines, health conditions, fitness and measurement error can change heart-rate response, so obtain individual professional guidance where appropriate.
How to use these calculators well
- Treat results as general screening estimates, not a diagnosis.
- Check whether the formula is appropriate for age, body type and health context.
- Discuss concerning or treatment-related results with a qualified health professional.
