Is an HRV of 75 ms good?
By Aditya Ganapathi · Co-Founder of Cora ·
An HRV of 75 ms is considered good to elite for most adults. At 75 ms, you are above the average for most adults. The average near the average for adults in their 20s (~75 ms) and well above average for all older age groups. This reading typically indicates excellent cardiovascular fitness, high parasympathetic tone, and strong recovery capacity.
How 75 ms compares to HRV averages by age
RMSSD (root mean square of successive differences) is the most common HRV metric reported by consumer wearables including Apple Watch, Garmin, Whoop, and Oura. Population averages from clinical studies and aggregated wearable data show a clear age-related decline — and significant individual variation at every age. The table below shows where 75 ms sits relative to each decade.
| Age Group | Average RMSSD | Typical Range | 75 ms is… |
|---|---|---|---|
| 20s | ~75 ms | 55–105 ms | near the average |
| 30s | ~62 ms | 45–85 ms | 13 ms above average |
| 40s | ~48 ms | 35–65 ms | 27 ms above average |
| 50s | ~38 ms | 25–55 ms | 37 ms above average |
| 60s | ~30 ms | 20–45 ms | 45 ms above average |

What an HRV of 75 ms typically indicates
An HRV of 75 ms RMSSD matches the population average for adults in their 20s — the highest-HRV age group in the population. For adults in their 30s and beyond, where averages decline to 62 ms, 48 ms, and lower, a reading of 75 ms represents exceptional autonomic health that places you well above your age-group peers.
Sustained readings at 75 ms require a combination of strong cardiovascular fitness, consistent quality sleep, effective stress management, and low alcohol consumption. Research published in the European Heart Journal has found that adults with RMSSD consistently above 65 ms have significantly lower rates of cardiovascular events over multi-year follow-up, suggesting that this range reflects genuine long-term health benefits beyond simple fitness markers.
For competitive endurance athletes, 75 ms is at the boundary of the recreational-to-competitive spectrum. Runners, cyclists, and triathletes who train 8–12 hours per week and prioritize recovery often see baselines in the 70–100 ms range. If you are here, your aerobic system and recovery habits are working well.

What to do about an HRV of 75 ms
- 1
Excellent baseline. The primary goal is maintenance through consistent habits: aerobic training, quality sleep, and stress management.
- 2
For athletes: if 75 ms is your typical baseline, it is a strong green signal for hard training days.
- 3
Be mindful of what produces this — protecting sleep and avoiding alcohol are the two most reliable levers for keeping HRV in this range.
- 4
Consider monthly tracking reviews to watch for gradual upward trends as training adaptations accumulate.
- 5
Cora can use your 75 ms baseline to provide personalized training readiness signals automatically.

Is 75 ms a great HRV number?
Yes. An HRV of 75 ms is excellent for most adults and matches the population average only for adults in their 20s. For anyone older, it represents outstanding autonomic health and places you in the top tier of your age group.
Is 75 ms HRV normal for a young athlete?
For young, fit adults in their 20s, 75 ms is near the population average. Trained athletes in this age group who specialize in endurance sports often see 80–110 ms. So for a competitive young athlete, 75 ms is healthy but there may be room for further improvement with training adaptation.
What HRV range do professional athletes have?
Elite endurance athletes — professional cyclists, marathon runners, triathletes — often report resting RMSSD values of 90–120 ms or higher, with exceptional individuals reaching 150+ ms. Strength-sport athletes tend to run lower (50–70 ms), as their sport emphasizes different physiological adaptations.
How do I know if 75 ms is high for me specifically?
Compare it to your own 30-day rolling average. If 75 ms is your consistent baseline, that is your healthy norm. If you typically see 55–65 ms and today you read 75 ms, it is an unusually high day — possibly driven by a measurement artifact or an especially restful night. Trend, not single readings, is what matters.
