What Is HRV and Why Does It Matter?
Heart Rate Variability (HRV) measures the variation in time between consecutive heartbeats. Higher HRV generally indicates better cardiovascular fitness and recovery status.
1. Know When to Push Hard
When your HRV is above your personal baseline, your body is primed for intense training.
2. Identify Overtraining Early
A sustained drop in HRV over several days can signal overtraining before you feel the symptoms.
3. Optimize Recovery Days
By tracking HRV during sleep and rest periods, you can see which recovery strategies actually move the needle.
4. Track Fitness Progress Over Time
As your cardiovascular fitness improves, you'll see a gradual upward trend in your baseline HRV.
5. Personalize Your Training Zones
Combining resting heart rate with HRV data allows for more accurate training zone calculation.
