For a 65-year-old, the Tanaka formula estimates a maximum heart rate of about 163 bpm. That puts your Zone 2 (easy aerobic) at roughly 98–114 bpm and your Zone 4 (threshold) at 130–147 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 65) |
|---|---|---|---|
| 1 | Recovery | 50–60% | 82–98 |
| 2 | Endurance | 60–70% | 98–114 |
| 3 | Aerobic | 70–80% | 114–130 |
| 4 | Threshold | 80–90% | 130–147 |
| 5 | Maximum | 90–100% | 147–163 |
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 65 |
|---|---|
| Fox (220 − age) | 155 |
| Tanaka (208 − 0.7 × age) | 163 |
| Gellish (207 − 0.7 × age) | 162 |
| Nes / HUNT (211 − 0.64 × age) | 169 |
| Gulati (206 − 0.88 × age, women) | 149 |
Typical resting heart rate: 58–76 bpm.
Typical VO2max reference (good/very good): Men 28–32 ml/kg/min (good); women 23–28 ml/kg/min (good). Source: ACSM norms and HUNT Fitness Study.
Why HRmax sits where it does at 65: Formula errors are largest at this age. Some 65-year-olds still hit 175 bpm on a field test; sedentary peers cap at 145. Do not train off a formula alone.
Four Zone 2 sessions of 30–40 minutes (walking or easy cycling), one Zone 4 session (3×5 min), and two strength/balance sessions.
Use them as population reference points for the age group, not as targets or thresholds. The trend in your own numbers over months is far more informative than where you sit in a table.
Using the Tanaka formula (208 − 0.7 × age), the estimated maximum heart rate for a 65-year-old is about 163 bpm. Population variability is roughly ±10–12 bpm, so your true HRmax could sit anywhere between 153 and 173 bpm.
Zone 2 for a 65-year-old is approximately 98–114 bpm, which corresponds to 60–70% of an estimated HRmax of 163 bpm. You should be able to hold a full conversation at this intensity.
Zone 4 (lactate threshold) for a 65-year-old is roughly 130–147 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.
Use them as population reference points for the age group, not as targets or thresholds. The trend in your own numbers over months is far more informative than where you sit in a table.
