What Is Maximum Heart Rate?

Maximum heart rate is the highest number of beats per minute the heart can reach during maximal physical effort. It is commonly estimated from age, using 220 − age or the Tanaka formula 208 − 0.7 × age, and it is the basis for calculating heart rate training zones.

Heart Rate Zones

Training zones are usually defined as percentages of maximum heart rate, from about 50%–60% (very light) to 90%–100% (maximum effort). The Karvonen method uses heart rate reserve (maximum minus resting heart rate) instead.

Accuracy

Age-based formulas are population averages and can differ from an individual's true maximum by 10 or more beats per minute; a supervised exercise test measures it directly.
