Founder & head coach

Built on work ethic, not natural talent.

I’ve competed at a high level in three very different sports. I came through elite basketball academies in the UK before earning a scholarship to Combine Academy in North Carolina, then competed in powerlifting at national level. Today I compete professionally in Muay Thai.

I’ve never been the most naturally gifted athlete. I got there through discipline, attention to detail and consistency — and that’s the standard I bring to every client, alongside evidence-based programming and the mental resilience that comes from competing.

Clients

In their words

“James understands that my time is precious. His sessions are efficient, targeted, and actually fit into my schedule. Beyond the training, he’s helped me build a nutrition strategy that works with my travel and client dinners — not against them. I’m stronger, more energetic, and frankly more confident in meetings.”

Sarah · Corporate lawyer

“As a dad with young kids, a long commute and a full-time job, finding time to train felt impossible. James gets it. He’s flexible when I need to reschedule, programmes workouts I can do at home when I can’t make the gym, and keeps me accountable without adding pressure. He practises what he preaches.”

Ben · Commercial property executive

“James brings the same elite-level approach to training that I bring to my work. His programming is intelligent, his nutrition advice is evidence-based, and his mindset coaching has genuinely improved how I handle stress and perform under pressure.”
