My mission: to redefine what fitness means

Fitness isn’t about a number on a scale or trying to “earn” confidence. It’s about how your body supports your life — lifting your kids without fear of injury, finishing the day with energy left in the tank, and standing a little taller because you finally trust yourself.

It's quiet confidence, built rep by rep. It's the confidence to go further than you thought you could — through a doorway, a doubt, or a finish line.

I know the other side — because I lived it

I didn’t grow up strong or athletic. I grew up as the fat kid — the one who avoided mirrors, hated P.E., and pretended not to care while quietly feeling humiliated. I remember the sting of being picked last, the anxiety of changing rooms, and the way you start to shrink yourself so no one notices you. These days, that same kid who dreaded P.E. and shrank into the changing-room walls trains for half marathons — not because he has to, but because he can. Thirteen miles, for the joy of it. Tell that to me at fifteen and I'd have laughed in your face. But that's what strength really is: build enough of it and it stops being about the gym at all. It becomes range. It becomes distance. It becomes a life that keeps getting bigger.

The weight I carried wasn’t just physical. It was emotional. It was social. It was identity.

Walking into a gym for the first time didn’t fix that overnight — but it changed the direction of my life. Strength training gave me the first real wins I’d had in years. It became proof that I could grow, that I wasn’t stuck, and that self-belief is something you build, not something you’re born with.

That confidence followed me into my personal and professional life. It changed how I show up. It changed who I believe I can be. And now, I help others find that same shift.

What I coach

I specialise in evidence-based strength training — the foundation everything else is built on — and hybrid coaching for people who want to take that strength somewhere: a race, a distance, a first finish line. Both are built on the same principles:

  • Compound movements: Mastering the basics that give the biggest return.
  • Progressive overload: A structured path to getting stronger, safely.
  • Technique first: Safety and longevity over ego lifting.
  • Resilience: Building a body and mind that can handle life’s challenges.
  • Conditioning that carries: Strength that holds up over miles, not just reps.

This isn’t about punishing yourself for the past. It’s about building a future you’re proud to grow into.

The mission of L.A.C. Fitness

Not to manufacture "athletes" or chase transformations for the algorithm — but to help people who feel how I used to feel, unseen and intimidated and stuck, discover what their bodies are actually capable of. Whether that's lifting with confidence or crossing a line they never thought they'd reach.

Because once you learn to lift, you learn to live differently.
