Overtraining: signs you shouldn't ignore

Overtraining is when training load persistently exceeds your recovery capacity. Paradoxical result: you train more, but you regress. Spotting it early prevents weeks or even months of underperformance.

Warning signs to watch for

• Declining performance despite consistent training.
• Fatigue that won't go away, even after rest.
• Elevated resting heart rate and declining HRV over several days.
• Degraded sleep, irritability, loss of motivation.
• Recurring infections, injuries piling up.

Normal fatigue or overtraining?

Significant fatigue after a heavy block is normal: it passes after a few easy days. Overtraining, on the other hand, persists despite rest. The difference comes down to duration and accumulation of signals.

How to respond

There's only one remedy: reduce load and recover — sometimes several days of rest, then a very gradual return. The longer you wait, the longer recovery takes. Sleep and nutrition are your best allies.

Preventing it: manage load and alternate

Alternate hard training and easy weeks (one lighter week every 3 weeks or so), respect 80/20 polarization, and monitor your indicators. Understanding TSB (freshness) helps you avoid staying in the red for too long.

An automatic safeguard

Sports Coach AI monitors your load, fatigue and recovery, and enforces an easy session or rest when your signals turn red — precisely to prevent overtraining.
