Does Any of This Sound Familiar?
- You used to thrive on hard training sessions — now you can barely finish them
- Your GP says your blood work is “normal”, but you feel anything but normal
- You’re exhausted yet wired, sleeping poorly, and losing motivation
- Brain fog, low mood, and emotional reactivity have become your baseline
- You’ve been told to “rest more” but nobody has given you an actual plan
- You’re a driven professional or athlete wondering if you’ve broken something permanent
If you’re nodding along, you’re not losing your mind. Your stress-response systems have been overloaded — and recovery requires more than a week off. The Recovery Code gives you the structured, evidence-based protocol to come back properly.

What’s Inside the Book
Part 1: Understanding the Problem
The science behind OTS and burnout — HPA axis dysregulation, autonomic dysfunction, hormonal collapse, and the gut-brain connection. Why your blood tests look “normal” when you clearly aren’t. How to recognise the early warning signs before the crash.
Part 2: The Recovery Blueprint
A structured 4-phase recovery protocol covering sleep optimisation, anti-inflammatory nutrition, HRV-guided movement, nervous system restoration, targeted supplements, and hyperbaric oxygen therapy. Including the TRT mistake — lessons learned the hard way.
Part 3: Rebuilding & Prevention
Tracking recovery metrics, preventing relapse with red/yellow/green rules, female-specific and masters-specific adjustments, ADHD and neurodivergence considerations, and the mindset framework to rebuild identity beyond performance.
What Makes This Different
Written From the Crash, Not the Classroom
Rohan didn’t just research OTS — he lived through a full HPA axis collapse after achieving a 27-year biological age reversal. Every protocol in this book was tested on himself first.
Functional Ranges, Not “Normal” Ranges
Goes beyond standard NHS reference ranges to explain optimal functional biomarker values — covering over 70 markers that mainstream medicine dismisses as “fine”.
A Structured Protocol, Not Generic Advice
Four distinct recovery phases with clear entry criteria, HRV-guided progression rules, and red/yellow/green thresholds — not just “rest more and eat better”.
ADHD & Neurodivergence Aware
Dedicated sections on managing recovery with an ADHD brain, including strategies for when the driven personality that caused the crash wants to rush the comeback.
Who Is This Book For?
Athletes & CrossFit Competitors
Who used to thrive on volume but now dread training — and can’t understand why sessions feel impossible when nothing has changed.
High-Achieving Professionals
Who’ve pushed through years of relentless demands and hit a wall that a holiday can’t fix — brain fog, fatigue, and emotional flatness.
Recreational Exercisers
Who train to stay sane and suddenly can’t — the stress budget is blown from life plus training, and everything has stopped working.
Healthcare Professionals
Looking for a practical, evidence-based reference on OTS and burnout recovery with clinical case studies, differential diagnosis, and implementation checklists.
Written by Someone Who Lived It
This isn’t theoretical advice from someone who read about overtraining in a journal. Rohan personally crashed into OTS, was failed by standard testing, and rebuilt using the exact protocols in this book. If it doesn’t resonate with your experience, get in touch — we’ll make it right.

Frequently Asked Questions
What format is the book in?
The Recovery Code is delivered as a PDF file, which works on every device — phone, tablet, laptop, or desktop. No special software needed. You can also print it if you prefer a physical copy.

What is overtraining syndrome (OTS)?
OTS occurs when cumulative physical and psychological stress exceeds your body’s ability to recover, leading to HPA axis dysregulation, hormonal imbalances, autonomic dysfunction, and a cascade of symptoms including chronic fatigue, mood disturbance, and performance collapse. Standard blood tests often come back “normal” despite significant dysfunction.
Is this book just for athletes?
No. The Recovery Code covers both overtraining syndrome and professional burnout. The underlying physiology — HPA axis dysfunction, cortisol blunting, and autonomic imbalance — is remarkably similar whether the stress comes from training or from professional demands. The book includes specific guidance for athletes, high-achievers, recreational exercisers, and healthcare professionals.
What is the 4-phase recovery protocol?
The Recovery Code provides a structured recovery timeline with four distinct phases, each with specific targets for sleep, nutrition, movement, and nervous system restoration. It includes HRV-guided decision rules, red/yellow/green thresholds, and metrics so you can track progress objectively rather than relying on how you feel.
Does this replace medical advice?
No. The Recovery Code is an educational resource based on clinical evidence and lived experience. It does not replace consultation with a qualified healthcare professional. If you’re experiencing persistent symptoms, please consult your GP or a specialist alongside using this book.
