Is an HRV of 70 ms good?
By Aditya Ganapathi · Co-Founder of Cora ·
An HRV of 70 ms is considered good for most adults. At 70 ms, you are above the average for most adults. The average above the average for adults in their 30s (~62 ms) and in the upper range for recreational athletes. This reading typically indicates excellent recovery, strong cardiovascular fitness, and high parasympathetic tone.
How 70 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 70 ms sits relative to each decade.
| Age Group | Average RMSSD | Typical Range | 70 ms is… |
|---|---|---|---|
| 20s | ~75 ms | 55–105 ms | near the average |
| 30s | ~62 ms | 45–85 ms | 8 ms above average |
| 40s | ~48 ms | 35–65 ms | 22 ms above average |
| 50s | ~38 ms | 25–55 ms | 32 ms above average |
| 60s | ~30 ms | 20–45 ms | 40 ms above average |

What an HRV of 70 ms typically indicates
An HRV of 70 ms RMSSD is an excellent reading for most adults. It exceeds the population average for adults in their 30s (62 ms), places you above the typical range for adults in their 40s (35–65 ms), and represents strong cardiovascular fitness relative to any adult age group. A sustained reading at 70 ms or above typically reflects a consistent aerobic training history, good sleep, and effective stress management.
Schumacher et al. (2022) characterize RMSSD values in the 65–80 ms range as reflecting high vagal tone with excellent autonomic regulation. At this level, your heart rate variability indicates that your parasympathetic nervous system is dominant at rest — the biological marker of good recovery readiness. Research has consistently linked sustained HRV in this range with favorable cardiometabolic health, higher aerobic capacity, and better long-term athletic performance outcomes.
For competitive endurance athletes, 70 ms sits at the lower end of what elite-level training often produces (80–120 ms range), but for recreationally active adults, 70 ms is in the top tier. If you have reached this baseline, the lifestyle factors responsible — sleep, Zone 2 training, low alcohol, stress management — are working well.

What to do about an HRV of 70 ms
- 1
Excellent baseline — maintain your current training and recovery practices consistently.
- 2
For competitive athletes: compare 70 ms against your personal norm. If typical for you, it is a clear green signal for hard training. If it is below your usual 80–90 ms range, consider a lighter day.
- 3
Protect sleep: this is the number-one factor keeping HRV in this range. A few nights of poor sleep can push a 70 ms baseline down to 50–55 ms temporarily.
- 4
Plan deload weeks: even at high HRV levels, planned recovery weeks every 4–5 training weeks prevent the cumulative load from eroding your baseline.
- 5
Continue monitoring with a rolling average — month-to-month trend is more meaningful than any single reading.

Is 70 ms HRV excellent?
Yes. For most adults, 70 ms RMSSD represents excellent autonomic health. It exceeds the average for all adult age groups and indicates strong cardiovascular fitness and high parasympathetic tone. Only elite endurance athletes routinely see values significantly above this.
Is 70 ms HRV normal for a 25-year-old?
For a 25-year-old, the population average is around 75 ms (range 55–105 ms), so 70 ms is slightly below average for that age group. It is still a strong reading — just at the lower half of what is typical for young adults. With consistent aerobic training, 25-year-olds often push into the 80–100 ms range.
Should I train hard with HRV of 70 ms?
If 70 ms is at or above your personal baseline, it is a green signal for hard training. If your typical range is 85–95 ms and you see 70 ms, that 15–25 ms drop is meaningful and suggests reducing today's session intensity.
Is 70 ms HRV enough for marathon training?
Yes. Many successful recreational marathon runners maintain HRV baselines in the 55–75 ms range. What matters for marathon training is the stability and trend of your HRV baseline alongside recovery metrics like sleep and resting heart rate — not a specific target number.
