Finding Your Maximum Heart Rate
What max heart rate is, why the 220 minus age rule is shaky, and how to estimate or field-test yours. Includes a six-formula calculator.
Your maximum heart rate (HRmax) anchors every heart-rate zone. Get it wrong by 10 beats and every zone shifts by 5–10 bpm.
What max heart rate is
HRmax is the highest your heart can beat during all-out effort. It is largely genetic, drifts down slowly with age, and is not a measure of fitness.
You can't train your max heart rate up. Its only job is to anchor your zones.
Estimate it in five seconds
The 220 − age rule is easy to remember but was never derived from solid data. It runs high for older athletes and low for some younger ones. Tanaka (208 − 0.7 × age) is more accurate. Drop your age in below to see six published formulas side by side:
Inirerekomendang HRmax
184bpm

Karaniwan ng lahat ng 6 na modelo
183bpm
kung hindi sigurado, gamitin ito
Anim na nailathalang predictor, magkatabi (±10–12 bpm na karaniwang error)
| Fox / Haskell (1971) | 185 bpm |
| Tanaka (2001)Inirerekomenda | 184 bpm |
| Gellish (2007) | 183 bpm |
| Nes (2013) | 189 bpm |
| Gulati, kababaihan (2010) | 175 bpm |
| Londeree & Moeschberger | 181 bpm |
| Karaniwan ng lahat ng anim na modelomean ng mga predictor sa itaas | 183 bpm |
- Inirerekomenda namin ang Tanaka (2001) dahil muli itong hinango mula sa meta-analysis ng 18,712 na tao at mas tumpak sa iba't ibang edad kaysa sa lumang 220 minus age na patakaran, na karaniwang sobra para sa mas matatandang atleta.
- Ang HRmax na hinula ng formula ay may standard deviation na humigit-kumulang ±10–12 bpm, kaya ang dalawang atletang magkakasing-edad ay maaaring magkaiba nang 20+ bpm. Gamitin ito bilang panimulang punto lamang.
- Para sa katumpakan, magsagawa ng maximal field test (hal. isang mahirap na hill-repeat session o isang supervised ramp test) at basahin ang tunay mong HRmax mula sa device.

Test it for real
A field test beats any equation. After a thorough warm-up:
- Run or ride 2–3 minutes hard uphill.
- Recover briefly, then go again, building to an all-out final 30 seconds.
- The highest number you see is close to your true HRmax.
Maximal effort, not for beginners. Stop if you feel unwell. One good test lasts years, since HRmax drops only about 0.7 bpm per year.
Then build your zones
- Heart-rate zone calculator: the standard %HRmax 5-zone split.
- LTHR zones: anchor to lactate-threshold heart rate instead.
- Max heart rate calculator: the six-formula tool above.
