Heart rate variability (HRV) is the variation in time between consecutive heartbeats. Higher HRV generally indicates better recovery and greater parasympathetic nervous system activity (rest and digest mode). Many athletes and coaches use morning HRV as a daily readiness metric. A sudden drop in HRV often signals illness, overtraining, or accumulated stress before other symptoms appear.

The most evidence-backed recovery accelerators are: adequate sleep (7–9 hours), protein intake within 2 hours of training, staying well hydrated, light active recovery (walking, stretching), managing overall life stress, and considering cold therapy or contrast showers. Fancy supplements are secondary to these fundamentals.

Take a rest day when your recovery score is below 40, when you feel unusual or persistent fatigue, when performance has declined across 2+ consecutive sessions, when your resting heart rate is elevated by 5+ beats, or when you're fighting off illness. Rest days aren't lost training days — they're when your body actually adapts and grows stronger.

Overtraining syndrome signs include: persistent fatigue that doesn't improve with rest, performance decline over 2+ weeks, elevated resting heart rate, frequent illness or infection, disrupted sleep (despite feeling exhausted), mood changes like irritability or depression, loss of motivation to train, and increased injury frequency. If you recognise several of these, take at least 1–2 weeks of full rest and consult a doctor.
