How to Calculate Maximum Heart Rate

Maximum heart rate (MHR) is the highest heart rate your cardiovascular system can achieve during intense exercise. It decreases with age and varies by individual. The classic formula is a starting point:

Max Heart Rate Formulas

  • Classic (Fox, 1971): MHR = 220 - age (most common, simple)
  • Tanaka (2001, more accurate): MHR = 208 - (0.7 x age)
  • Gellish (2007): MHR = 207 - (0.7 x age)

Example for a 35-year-old: Classic = 185 bpm, Tanaka = 183.5 bpm

Zone 3 – Moderate70–80%Cardiovascular endurance
Zone 4 – Hard80–90%Anaerobic threshold, speed
Zone 5 – Maximum90–100%Peak performance, intervals

Resting Heart Rate

Resting heart rate (RHR) is a good indicator of cardiovascular fitness:

  • Untrained adult: 70–80 bpm
  • Fit adult: 50–65 bpm
  • Elite endurance athlete: 30–50 bpm

Using RHR with MHR in the Karvonen formula gives a more precise training zone (Heart Rate Reserve method).

Frequently Asked Questions

It is the most common estimate for maximum heart rate. It has a standard deviation of ±10-12 bpm, so actual MHR can vary significantly from person to person.
Zone 2 (60-70% MHR) burns the highest percentage of calories from fat. Zone 4-5 burns more total calories but a lower fat percentage.
HRR = Max HR - Resting HR. The Karvonen formula uses HRR to calculate training zones more personalized than the simple percentage method.
