For a 30-year-old, the Tanaka formula estimates a maximum heart rate of about 187 bpm. That puts your Zone 2 (easy aerobic) at roughly 112–131 bpm and your Zone 4 (threshold) at 150–168 bpm. Below you will find the full 5-zone table, a formula comparison, and a calculator that personalises the numbers if you enter your resting HR.
| Zone | Name | % HRmax | BPM (age 30) |
|---|---|---|---|
| 1 | Recovery | 50–60% | 94–112 |
| 2 | Endurance | 60–70% | 112–131 |
| 3 | Aerobic | 70–80% | 131–150 |
| 4 | Threshold | 80–90% | 150–168 |
| 5 | Maximum | 90–100% | 168–187 |
No single equation is authoritative. The spread below shows why picking a formula matters — the difference between Fox and Nes at your age moves your Zone 2 ceiling by several beats.
| Formula | HRmax at age 30 |
|---|---|
| Fox (220 − age) | 190 |
| Tanaka (208 − 0.7 × age) | 187 |
| Gellish (207 − 0.7 × age) | 186 |
| Nes / HUNT (211 − 0.64 × age) | 192 |
| Gulati (206 − 0.88 × age, women) | 180 |
Typical resting heart rate: 55–70 bpm.
Typical VO2max reference (good/very good): Men 41–48 ml/kg/min (good); women 34–40 ml/kg/min (good). Source: ACSM norms and HUNT Fitness Study.
Why HRmax sits where it does at 30: HRmax has dropped roughly 5 bpm from age 20 for most adults. Aerobic capacity also tends to decline gradually with age, and regular endurance training is associated with a slower decline.
Three Zone 2 sessions of 40–60 minutes, one Zone 4 threshold session, and strength twice weekly. If time is truly short, prioritise the Zone 2 volume over the quality day.
Population averages drop about 5 bpm from age 20 to 30, but individual variation is ±10 bpm. Genetics matter more than age within any decade.
For general health, yes. To preserve VO2max — the strongest predictor of longevity — add one Zone 4 or Zone 5 session per week (4–8 minute intervals work well).
Using the Tanaka formula (208 − 0.7 × age), the estimated maximum heart rate for a 30-year-old is about 187 bpm. Population variability is roughly ±10–12 bpm, so your true HRmax could sit anywhere between 177 and 197 bpm.
Zone 2 for a 30-year-old is approximately 112–131 bpm, which corresponds to 60–70% of an estimated HRmax of 187 bpm. You should be able to hold a full conversation at this intensity.
Zone 4 (lactate threshold) for a 30-year-old is roughly 150–168 bpm — 80–90% of HRmax. At this intensity you can only speak in short phrases.
Enter your resting heart rate into the calculator to apply the Karvonen method, which anchors zones to your heart rate reserve. This is significantly more accurate than %HRmax alone, especially if you are trained or untrained.
Population averages drop about 5 bpm from age 20 to 30, but individual variation is ±10 bpm. Genetics matter more than age within any decade.
For general health, yes. To preserve VO2max — the strongest predictor of longevity — add one Zone 4 or Zone 5 session per week (4–8 minute intervals work well).
