HRV-guided training uses daily morning HRV readings relative to personal baseline to determine training intensity. Above baseline (green) = high intensity appropriate; near baseline = normal training; below baseline (red) = prioritise recovery. Systems like WHOOP, Garmin Body Battery and Polar Recovery Pro automate this tracking. Research shows HRV-guided training produces similar or better fitness gains than traditional periodisation while reducing illness and injury rates. The key is individual baseline — never compare absolute HRV numbers to others.
Key points
- Daily HRV vs personal baseline
- Green = train hard; red = recover
- Automates training load decisions
- Reduces illness and overtraining risk
