Signs You Need More Recovery
Watch for soreness beyond 72 hours, falling performance, elevated resting heart rate, disrupted sleep, frequent illness, or vanished motivation. Those are under-recovery signals.

The mistake most enthusiastic trainees make is adding more training when progress stalls, when the answer is usually more recovery. A week of reduced training often produces a performance breakthrough because the body finally has time to complete its repair processes.
