More and more coaches are using simple physiological markers to guide training decisions. Wearables now give actionable overnight insights — sleep duration/architecture, resting heart rate, and heart-rate variability (HRV) — metrics that can predict readiness and help time intense sessions. Studies in 2024–2025 highlight how monitoring sleep and HRV can improve recovery planning and reduce overtraining risk when used responsibly.
Practical policies for Lodestar: ask athletes to track sleep for 2–3 weeks to establish baselines, then use simple traffic-light rules. If HRV and sleep are within normal ranges, proceed as programmed. If HRV drops substantially and sleep is poor, switch to skill + mobility or a short aerobic session. Don’t over-react to single nights; look for trends.
Also coach sleep hygiene: consistent bedtimes, device curfews, and caffeine timing are training tools. Recovery isn’t optional — it’s where strength and adaptations actually consolidate.
