Heart Rate

Calculate your target and maximum heart rate zones.

Formula & Methodology

Maximum heart rate ≈ 220 − age; target zones are percentages of that maximum.

Worked Example

A 30-year-old has an estimated max heart rate of 190 bpm, with a moderate zone of about 114–133 bpm.

Frequently Asked Questions

How is max heart rate estimated?

A common formula is 220 minus age, though individual variation is large. Other formulas like Tanaka (208 − 0.7 × age) are also used.

What is a target zone?

A percentage range of max heart rate to train in, such as 50–70% for moderate intensity or 70–85% for vigorous intensity.

Is this medical advice?

No. Heart rate targets vary with fitness and health conditions. Consult a provider before starting intense training.
