Training stress is necessary, but adaptation only happens when the nervous system can recover. Without parasympathetic balance, even the best training programs eventually stall.
Chronic sympathetic dominance impairs sleep, digestion, and recovery.
Deep sleep supports hormonal regulation, tissue repair, and nervous system reset.
Heart rate variability reflects nervous system resilience and recovery capacity.
Key Takeaway: Recovery is neurological before it’s muscular. Train hard, but recover smarter to sustain long-term performance.
