Maximum Heart Rate

Your estimated maximum heart rate, and the training zones under it.

How this is worked out

"220 − age" is the best-known formula and the weakest: its standard deviation is around ±11 beats. Tanaka et al. (2001) fits adult data better, so both are shown. Zones use the Karvonen method, which accounts for your resting rate. If you take heart medication — beta blockers especially — these numbers do not apply to you; ask your doctor.
