Performance Coaching Built Around What
Your Body Is Actually Telling You.

ABOUT HARRISON FLEETWOOD

Performance coach, functional bloodwork practitioner, and strength athlete. Based in the UK, working with athletes and high performers who are doing everything right but not adapting the way they should.

THE BACKGROUND

WHERE THIS
STARTED.

I have been a competitive strength athlete for over a decade. In that time, one thing became clear: most coaching focuses on performance, but rarely on what keeps it sustainable.

The gap between health, longevity, and performance is where I found my purpose. I watched athletes push harder, change programmes, rotate supplements, and still plateau, not because they lacked effort, but because nobody was looking at the underlying system.

Gut function was ignored. Hormonal baselines were dismissed as "normal." Fatigue was blamed on stress without measurement.

I started coaching to bridge that divide. I trained as a Functional Blood Work Practitioner, Hormone Health Coach, and Naturopath specifically because the tools I needed to do this properly did not exist in standard performance coaching.

I now work with athletes, executives, and high performers who feel like they are doing everything right but not adapting the way they should.

The methodology is the same across all of them: investigate the system before adjusting the output.

QUALIFICATIONS

The Certifications
Behind the Work.

IOH Certified
Functional Blood Work Practitioner

Trained to interpret blood markers as dynamic signals within performance and stress context, not as pass/fail diagnostics against population reference ranges.

Certified
Hormone Health Coach

Specialising in hormonal optimisation across both male and female physiology, including TRT management, perimenopause, PCOS, and cycle-based performance.

Certified
Testosterone Deficiency Management

Qualified to support clients navigating TRT and hormonal protocols, with a focus on optimising the full hormonal environment rather than isolated testosterone values.

Certified
Naturopathy Practitioner

Grounding clinical interpretation in a whole-system framework, addressing root causes across nutrition, lifestyle, and physiology rather than managing symptoms in isolation.

HOW I WORK

The Old Model

Isolated markers. Reactive fixes.

Bloodwork treated as pass/fail. “In range” equals fine. Hormones adjusted without context. Fatigue blamed on stress without measurement. Training reduced without identifying the signal.

The Framework

Pattern recognition. Input first.

Bloodwork read as a dynamic signal. Trends interpreted against stress load and recovery demand. Activated vs suppressed system states identified. Inputs stabilised before optimisation begins.

“Progress doesn’t stall because you lack discipline. It stalls because the body is operating in a constrained state. Without identifying that state, coaching becomes guesswork.”

Normal Doesn't
Mean Optimal.

Built For

Right Fit.

  • Athletes who train hard but are not adapting the way they should

  • Anyone who has been told their bloodwork is “normal” but still feels off

  • Competitive athletes, natural or enhanced

  • Those navigating hormonal dysfunction, perimenopause, or chronic stress

  • High performers who want precision, not guesswork

  • Anyone willing to execute consistently across 12 weeks

Not Built For

Wrong Fit.

  • People looking for a generic meal plan or macro template

  • Anyone wanting a quick fix without structural change

  • Those unwilling to commit to the full 12-week process

  • Casual interest without real intent to act

I am not a physique coach. If the goal is a generic cut for a holiday, this is not the right fit. If the goal is understanding and optimising how your system actually functions, it is.
