What HRV can tell you about training readiness
Heart Rate Variability (HRV) is a direct window into your autonomic nervous system. A drop in HRV indicates your body is still absorbing stress, meaning hard intervals might do more harm than good.
- High HRV indicates biological readiness for intense efforts
- Low HRV signals system fatigue, indicating recovery is needed
- Averages and baseline trends are analyzed, not just single days
