Max Heart Rate for a 43-Year-Old Man
The Tanaka formula estimates a maximum heart rate of about 178 bpm for a 43-year-old man. Population variability is roughly ±10–12 bpm, so your true HRmax could sit anywhere between 168 and 188. This page compares the five main formulas at your age and shows how the difference propagates into your training zones.
Estimated HRmax
Tanaka estimate for a 43-year-old man: 178 bpm. Likely range 168–188 bpm.
All Five Formulas at Age 43
| Formula |
HRmax at age 43 |
| Fox (220 − age) | 177 |
| Tanaka (208 − 0.7 × age) | 178 |
| Gellish (207 − 0.7 × age) | 177 |
| Nes / HUNT (211 − 0.64 × age) | 183 |
| Gulati (206 − 0.88 × age, women) | 168 |
For men, Tanaka (2001) is a strong general-purpose choice, though Nes may fit better if you are highly trained.

Frequently Asked Questions
What is the maximum heart rate for a 43-year-old man?
The Tanaka formula estimates a maximum heart rate of about 178 bpm for a 43-year-old man. Your true HRmax is likely between 168 and 188 bpm.
Which formula is most accurate for a 43-year-old man?
Tanaka (2001) is a strong general-purpose choice for men over 40. Nes (HUNT) may fit better if you are highly trained. Fox (220 − age) tends to overestimate HRmax for active men.
Why do the five formulas give different results?
Each formula was derived from a different study population. Genetics account for roughly 50% of individual variation in HRmax, so no single equation fits everyone. A supervised maximal effort test is the only way to know your true HRmax.
Can I measure my real HRmax at home?
Yes, if you are healthy and cleared for vigorous exercise. Warm up thoroughly, then perform a 3–5 minute all-out effort finishing with a 30–60 second sprint. Record the peak value on a chest strap monitor. Do not attempt this if you have a heart condition or are on rate-limiting medication.
