Your longevity numbers at 37
The heart rate, fitness, sleep and protein numbers that matter at 37, worked out from the same sourced formulas as our free tools. Treat them as a starting point, then make them yours with the calculators.
Max heart rate and Zone 2 at 37
Estimated maximum heart rate: 182 bpm (208 − 0.7 × 37). Zone 2 by the simple method, 60–70% of that: 109–127 bpm.
With your resting heart rate, the heart-rate-reserve method gives a more personal Zone 2:
| Resting HR | Zone 2 |
|---|---|
| 50 bpm | 129–142 bpm |
| 60 bpm | 133–145 bpm |
| 70 bpm | 137–148 bpm |
All five heart rate zones at 37
| Zone | Range |
|---|---|
| 1 · Very easy | 91–109 bpm |
| 2 · Easy (Zone 2) | 109–127 bpm |
| 3 · Moderate | 127–146 bpm |
| 4 · Hard | 146–164 bpm |
| 5 · Maximum | 164–182 bpm |
VO2max at 37: what is typical
These are the FRIEND registry percentiles for ages 30–39, from treadmill tests in healthy adults (ml/kg/min).
| 25th | 50th (median) | 75th | 95th | |
|---|---|---|---|---|
| Female | 25.3 | 30.2 | 36.1 | 45.8 |
| Male | 35.9 | 42.4 | 49.2 | 59.8 |
Across the next decade the median drops from 42.4 to 37.8 for men and from 30.2 to 26.7 for women. Training is how you stay ahead of that curve.
Sleep at 37
The National Sleep Foundation recommends 7–9 hours a night for adults aged 26 to 64.
Movement targets at 37
WHO recommends 150–300 minutes of moderate activity a week, or 75–150 vigorous, or a mix, plus muscle-strengthening on 2 or more days.
Protein at 37
For someone who trains regularly and wants to keep their muscle, our protein calculator gives:
| Body weight | Per day | Per meal |
|---|---|---|
| 60 kg | 85–110 g | ≈ 25 g |
| 70 kg | 100–125 g | ≈ 30 g |
| 80 kg | 110–145 g | ≈ 30 g |
| 90 kg | 125–160 g | ≈ 35 g |
Questions people ask
What is a good Zone 2 heart rate for a 37-year-old?
About 109–127 bpm by the simple method: 60–70% of an estimated maximum of 182 bpm (208 − 0.7 × age). With a resting heart rate of 60, the heart-rate-reserve method gives 133–145 bpm. The talk test is the check: full sentences, but you would rather not sing.
What is the maximum heart rate for a 37-year-old?
About 182 bpm from the Tanaka formula, 208 − 0.7 × age. It is an average for the age: individual maximums often sit well above or below it, so a measured value is better when you have one.
What is a good VO2max at 37?
In the FRIEND registry of treadmill tests, the median for ages 30–39 is 42.4 ml/kg/min for men and 30.2 for women. The 25th to 75th percentile runs from 35.9 to 49.2 for men and from 25.3 to 36.1 for women.
