BEHIND YOUR NUMBER

A little understanding
goes a long way.

How is max heart rate estimated?

We use the Tanaka formula, 208 − 0.7 × age, which is more accurate than the older 220 − age. A measured max from a hard test is better still.

What is the Karvonen method?

It uses your heart rate reserve (max − resting), so zones reflect your fitness. Fitter people with a low resting heart rate get higher zone boundaries.

Target = resting + % × (max − resting)

Is this calculator for me?

It suits most healthy adults. Results are estimates. If you have a heart condition, are pregnant or are new to exercise, check with your GP before increasing your activity.
