Why I Coach
My journey into the health and fitness industry didn't begin with success - It began with struggle.
From a young age, sport was my life. I grew up playing football and competing in athletics as a sprinter, even training alongside athletes who went on to compete at the Olympics. Training in that environment showed me what efficient, high-level programming really looks like.
But with joys came setbacks. By the time I was 21, I had already undergone two knee surgeries from recurring injuries that forced me to step away from sport completely. My body wasn’t playing ball, and it was a tough reality to accept, but it also became a turning point.
I became determined to figure out how the body really works — how to train efficiently, avoid setbacks, and build lasting results that don’t come at the cost of your health. That journey is what led me into coaching.
Now, I help people who feel frustrated, stuck, or limited by their bodies unlock their full potential — so they can get strong, lean, and confident without sacrificing their joints, energy, or lifestyle along the way.
The LJL Fitness Approach
I created LJL Fitness in 2014 to help busy professionals regain control of their health amidst demanding careers. Over the last decade, I’ve developed a holistic, science-backed coaching system that delivers more than just a physical transformation. My clients don’t just lose fat or build muscle — they gain energy, confidence, and resilience that carries into their careers, relationships, and everyday life.
I don't believe in a generic ,one size fits all approach. Every element of your plan - training, nutrition & mindset is custom built to align with your lifestyle and goals. I relentlessly focus on what actually works - no fad strategies, just proven systems for elite results.
This isn’t about quick fixes or unsustainable methods. It’s about building long-term results that you can maintain — no matter how busy life gets.

THE TYPE OF CLIENT I LOVE TO WORK WITH...
Most of my Slough personal training clients are busy executives and entrepreneurs who are excelling in their careers — but neglecting their health. They come to LJL Fitness motivated to break the cycle of destructive habits and finally give their body the time, energy and focus it deserves.
If you’re coachable, accountable, and and 100% READY to invest in yourself, then it’s very likely I can help you. My role is to provide the blueprint, guidance and accountability - your role is to execute. When we combine those two, your results will speak for themselves.
