Performance Science Lab
Monitoring lab
Monitoring is useful when it changes decisions: training load, recovery signals, and pacing control.
Start here
- • A metric is only good if it changes behavior (not anxiety).
- • Trend > point: weekly averages beat single-night readings.
- • Use monitoring to avoid overreach and to time intensity weeks.
