Vol. 13 — Stress, Cortisol & The Nervous System

Cortisol isn't the villain the internet sells. Chronic stress, though, quietly eats your training.

Six chapters map stress from the inside: acute versus chronic, how stress and training pull on the same rope, and the HPA axis that ties it together — in plain language, not lab jargon. You'll get usable tools — breathwork, nervous-system recovery methods — and, just as important, the line where stress stops being a training variable and becomes medical. Cortisol has been turned into a marketing boogeyman. This gives you the real picture, so you can manage the load instead of fearing a single hormone.

Includes the complete audiobook (MP3, AI-narrated).
