Sound familiar?

You're not failing
at fitness.

You're failing at consistency. And that's a different problem — one that a new programme won't fix on its own.

"I've joined three gyms in five years. I go hard for six weeks, then something comes up — work, life, a bad week — and I stop. Every time."
📱
"I follow the programmes, watch the videos, track my food. I know what to do. But I'm still in the same place I was two years ago."
🏋️
"I turn up. I put the work in. But I'm winging it — copying what others are doing, never sure if it's actually building toward anything."
⏰
"I'm in my 30s, desk job, two kids. I want to be strong and actually move well — not just lose weight. I just need someone to show me how."
"The gym is the vehicle. Who you become is the destination."

12 weeks. Three phases. A different version of you — in every room.

"He introduced me to flow movement, rope flow, and jiu-jitsu — which has been genuinely life-changing. It's so much more than just training."

The journey

What 12 weeks of
coaching with Jerome looks like.

Three phases. Four weeks each. Jerome works with you in person at The Gym Group Sydenham — the physical work and the personal shift happen at the same time. That's not a coincidence, it's the method.

Phase 01 · Weeks 1–4
Foundation
who you're becoming

Before any lifts, we find out what you're working with. Seven fundamental movements. Physical limitations, mental blocks, the fears that hold you back. This is where we build the real foundation.

Phase 02 · Weeks 5–8
Strength
how you train

Compound lifts, progressive loading, the numbers going up. You get objectively stronger. Belief starts to catch up with the body.

Phase 03 · Weeks 9–12
Performance
what you're capable of

Kettlebells, functional training, compound work combined. Demanding by design. This is where it clicks — you're not just strong, you move like it.

12 weeks. Three phases. Reviewed and reset at the end of every cycle.

Jerome Marshall — Strength & Movement Coach
The method behind the results

About Jerome

I'm Jerome — a strength and movement coach based in SE London. My background is in martial arts, and that shaped everything about how I coach. Not the techniques. The mindset. The willingness to show up when you don't feel ready.

I know what it costs to build an identity from scratch. That's why I take this work seriously — and why I understand that for most people, the real barrier isn't physical. It's the story you're carrying about who you are.

I use physical training as the vehicle. The destination is who you become — someone who acts, who shows up, who doesn't second-guess themselves out of the room. I work with adults over 30 who are physically capable but mentally held back. My job isn't to make you fitter. It's to make you someone different.

"Most people don't have a fitness problem. They have an identity problem. The gym is just where we fix it."
