Heart rate variability (HRV) is your body’s readiness signal. High HRV = train hard, low HRV = recover.
What is HRV?
Variation in time between heartbeats. Higher = better recovery and readiness.
How to Measure
Use Oura, Whoop, or chest strap + app. Measure first thing in morning for 2-5 minutes.
Training Decisions
High HRV: Train hard. Baseline HRV: Normal training. Low HRV: Easy day or rest.
Conclusion
Track HRV daily for 2 weeks to establish baseline, then use for training decisions.
