Hi, I'm Gareth.

"I've lived every side of this — the discipline of pro sport, the shock of losing it all, and the climb back. The package you're looking at today is the one I built on myself first."

Football has been my whole life. From academy days as a kid through to professional level — every early morning training run, every weekend match. I never stopped playing, even into my forties. Then at 40, I snapped my Achilles. The playing stopped. The training stopped. I put on three stone in weight and genuinely didn't recognise myself.

The comeback started in group PT sessions — small wins, weight coming off, confidence returning. That journey led me straight into my personal training and nutrition diplomas. I used myself as the test case, refining what actually works until I'd built the complete system you see here today. All while raising my two boys (16 and 12) as a single dad — so trust me when I say this system has to work around real life.

Every method, every principle, every phase of this programme has been tested on me before it ever reached a client. That's why it works — and why this is the smallest investment you can make in yourself for the biggest return.

Why Most People Fail

Not big. Just lean.

Most people either train too heavy and bulk up, or crash diet and lose all their muscle. The Fight Club physique needs both sides dialled in at the same time. That's what Gareth does — and almost nobody else does it well.

01

Built around your exact goal

Your programme is written from scratch, not pulled off a shelf. Gareth builds it around your schedule, training history, and the specific body fat percentage you want to hit.

02

Lose fat without losing muscle

Getting lean without looking depleted is a nutrition problem first. Gareth keeps protein high and your deficit calculated — so you reveal muscle, not just shed weight.

03

Adjusted every single week

Plateaus happen when nothing changes. Gareth reviews your check-in every week and adapts your plan — so progress keeps moving regardless of what life throws at you.

04

No treadmill. No gym required.

No endless cardio. No forced gym sessions. Your workouts are built around your environment — home, gym, hotel room, it doesn't matter. Short, effective sessions you'll actually stick to.

Why 12 Weeks on Full Transformation?

Real transformation doesn't happen in 4 weeks — it takes a full cycle for training, nutrition and habits to lock in. Gareth only takes on Full Transformation clients serious about committing to the full process. Nutrition Only runs monthly with no lock-in.

The Gareth Guarantee
Do the work. Get results — or your money back.

If you complete every weekly check-in and hit your training and nutrition targets, but aren't seeing measurable progress by week 6, the next month is on me. Fair on both sides.

How the Guarantee Works
  • You complete every weekly check-in through the MyPTHub app — no missed weeks.
  • You hit your training and nutrition targets at 80% or higher. The data is in the app, so it's straightforward to verify.
  • If by week 6 you're not seeing measurable physical progress, contact Gareth and the next month's payment is refunded — no awkward conversations.
  • This guarantee exists because Gareth knows the system works when it's followed. It's there to protect committed clients, not give chancers a free trial.

By proceeding with payment, you confirm you've read the Client Agreement and Terms, and acknowledge you should consult your GP before starting any new exercise or nutrition programme — particularly if you have any pre-existing conditions or injuries.

That's exactly what Gareth specialises in. Your programme is built around your current ability, not someone else's. Whether you're starting from scratch or coming back after years out, the plan is calibrated to where you are now — and progressed safely from there.
No. Programmes are built around your environment — full commercial gym, basic home setup with dumbbells, or even bodyweight if needed. Tell Gareth what equipment you have access to during onboarding and he'll design around it.
Gareth has lived this himself — coming back from a snapped Achilles at the age of 40. Programmes work around injuries with smart exercise selection and progressive loading. Disclose anything during onboarding and your plan will be built to protect what needs protecting while still moving you forward.
Yes. The programme is built around your schedule, not the other way around. Hotel-room workouts, flexible meal frameworks, adjustments around late nights — Gareth has coached shift workers, frequent travellers, and parents with chaotic schedules. The system flexes to fit your life.
You can continue month-to-month at the same rate, take a break and come back later, or graduate to a maintenance phase. Most clients stay on for multiple cycles — the system keeps evolving with your goals. No surprise charges, no hidden fees.
A typical gym PT sees you 1–3 hours a week and that's it. With Gareth you get a full 168-hour-a-week system — training, nutrition, accountability, weekly adjustments, messaging support. Plus you're not paying gym PT rates of £40–60 per session. The maths works heavily in your favour.

Your Cortisol Risk
LowModerateHigh
What's your cortisol score?

A free assessment that scores your stress, sleep and lifestyle — and shows where chronic cortisol could be sabotaging your fat loss.

Free Assessment

Eating less and still stuck?

Most people who plateau aren't lazy — they're under-eating. Drop calories too aggressively and your body raises cortisol to protect itself. The fat stays put. Sleep suffers. Cravings spike. Take the assessment to see if it's happening to you.

  • 10 questions across sleep, stress, training and lifestyle
  • Personalised cortisol risk score (out of 10)
  • Tailored recommendations based on your answers
  • Full PDF report sent to your inbox
