Your longevity numbers at 43
The heart rate, fitness, sleep and protein numbers that matter at 43, 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 43
Estimated maximum heart rate: 178 bpm (208 − 0.7 × 43). Zone 2 by the simple method, 60–70% of that: 107–125 bpm.
With your resting heart rate, the heart-rate-reserve method gives a more personal Zone 2:
| Resting HR | Zone 2 |
|---|---|
| 50 bpm | 127–140 bpm |
| 60 bpm | 131–143 bpm |
| 70 bpm | 135–146 bpm |
All five heart rate zones at 43
| Zone | Range |
|---|---|
| 1 · Very easy | 89–107 bpm |
| 2 · Easy (Zone 2) | 107–125 bpm |
| 3 · Moderate | 125–142 bpm |
| 4 · Hard | 142–160 bpm |
| 5 · Maximum | 160–178 bpm |
VO2max at 43: what is typical
These are the FRIEND registry percentiles for ages 40–49, from treadmill tests in healthy adults (ml/kg/min).
| 25th | 50th (median) | 75th | 95th | |
|---|---|---|---|---|
| Female | 22.1 | 26.7 | 32.4 | 41.7 |
| Male | 31.9 | 37.8 | 45.0 | 55.6 |
Across the next decade the median drops from 37.8 to 32.6 for men and from 26.7 to 23.4 for women. Training is how you stay ahead of that curve.
Sleep at 43
The National Sleep Foundation recommends 7–9 hours a night for adults aged 26 to 64.
Movement targets at 43
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 43
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 43-year-old?
About 107–125 bpm by the simple method: 60–70% of an estimated maximum of 178 bpm (208 − 0.7 × age). With a resting heart rate of 60, the heart-rate-reserve method gives 131–143 bpm. The talk test is the check: full sentences, but you would rather not sing.
What is the maximum heart rate for a 43-year-old?
About 178 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 43?
In the FRIEND registry of treadmill tests, the median for ages 40–49 is 37.8 ml/kg/min for men and 26.7 for women. The 25th to 75th percentile runs from 31.9 to 45 for men and from 22.1 to 32.4 for women.
