Estimate five training zones from age and resting heart rate.
Preparing calculator…
Age-predicted maximum heart rate is a population average and can miss an individual value by 10 bpm or more. Wearables can also lag.
Not a diagnosisFor general health education and estimation only. It does not diagnose a condition and is not treatment, medication, diet or training advice.
target HR = (HRmax − HRrest) × intensity + HRrestGenerally healthy adults making a rough aerobic-intensity plan.
Heart disease, pregnancy, medicines that affect heart rate or a medical exercise restriction require individual guidance.
Input accuracy, measurement technique, rounding and individual variation all affect the result. Internal precision is retained and only displayed values are rounded.
Stop immediately for chest pain, fainting, irregular heartbeat or unusual breathlessness; seek urgent care when appropriate.
