Max Heart Rate
Max heart rate by 220 − age (bpm).
How it works
Max HR = 220 − age
Max heart rate is the approximate safe upper limit of heart rate during exercise, used to set training intensity. A more precise alternative is Tanaka: 208 − 0.7×age.
FAQ
Why 220 minus age?
220 − age is a simple population-based approximation; individual variation can reach ±10–15 bpm, so treat it as a guide.
Worked example
Age 30 with 220 − age: 220 − 30 = 190 bpm.
Tanaka (more accurate): 208 − 0.7 × 30 = 187 bpm. A three-beat difference is normal.
Notes and limitations
Population error is about ±10–12 bpm and individual variation is large. Beta-blockers and similar medication lower heart rate substantially, making the formula unreliable. Use a graded exercise test when precision matters.
