Max Heart Rate Calculator
Estimate your HRmax with 5 scientific formulas. Compare results to find the value best suited to your profile.
Maximum heart rate (HRmax) is the highest number of beats your heart can reach per minute during maximal exertion. It's a fundamental value for calculating your training zones. Since a true HRmax test (maximal effort on a treadmill under medical supervision) isn't always feasible, several age-based formulas can estimate this value. Each formula has its strengths: some are validated on large populations, others are gender-specific. This calculator compares 5 formulas and recommends the most suitable one for you.
