CAL.507 starts in 2014, the year I left the British Army after 23 years and started again. The date on the wordmark is not decoration. It is when the second career began.

It started long before that. From about eight years old I was obsessed with muscles, and by eleven I was already flexing. At 16 I became a soldier, and I spent the next 23 years with the 1st Battalion, The Royal Regiment of Fusiliers. I was the battalion boxing champion. Bosnia, at 20, taught me I was not bulletproof. The Army built more than fitness. It gave me discipline, respect, loyalty, teamwork and the ability to adapt, and a line I still live by: change the plan, never the goal.

Training was part of my life the whole way through. I spent years writing programmes for friends, sorting their food out and answering their questions. I never wanted to be a PT in the Army though. I wanted to be a soldier, and I was one. It took my wife asking why I did not do it for a living for the obvious to land, and during my final tour it felt like the natural next step. By the time I handed my kit in, the next career was already mapped out. Personal training chose me. I did not choose it.

I competed for the first time that same year, at the British Isles Championships, and won the first timers class. Since then I have been on stage with NABBA, the IBFA and the PCA, through British titles, a world championship and a Mr Universe. None of it happened alone. Coaches, mentors, team mates and family all matter, and the only comparison I make is me against me. The rest I leave to the judges.

The parts that made me a better coach were the parts that went wrong. In 2018, through the Mr Universe and the IBFA World Finals in Rome, I trained too much and ate too little for too long. My biggest defeat that year was not losing. It was ignoring what my body was telling me.

Then a blood test changed everything. Looking healthy and being healthy turned out not to be the same thing. Now I measure, act on what I find and test again, and I tell everybody I coach the same: do not wait until you are ill to take your health seriously. Get your blood work done.

After five years away I went back on stage in 2023 and won again, taking both the masters over 40 and the light heavyweight classes at the Viking Classic. I was stronger because I trained smarter, not simply more.

What keeps me doing this is not the physiques. In 2014 I got a message from a client's mum telling me what had changed for her daughter: she was eating properly, she had lost weight, and she had her confidence back. That message reset the job for me. Coaching is not just weight loss either. Some of the best wins have been cholesterol coming down and type 2 diabetes going into remission, achieved alongside the client's own medical team. It is not the trophies I will remember. It is the people. When my clients win, I win.
