After years of competing, coaching, recovering from injuries, and helping others transform their lives, Sam and his partner Jules created AK37 to bring together everything he's learned about strength, resilience, recovery, and personal growth.

Today, he works with clients around the world, helping them become stronger physically, mentally, and emotionally.

WHERE PASSION BECAME PURPOSE

The BEGINNING

From a young age, everything revolved around pushing limits. Every decision, every sacrifice, every early morning and late night was made in pursuit of becoming better tomorrow than he was today.

Sam did things others wouldn’t so he was able to do things others couldn’t.

The opportunities that followed were things most athletes only dream about: magazine covers, international trade shows, sponsorships, featured athlete at expo’s like BodyPower and years spent working alongside some of the biggest names in the industry. The current and 3x Mr Olympua Ryan Terry, Arnold Classic champion William Bonac, Big Ramy, Jay Cutler, Ronnie Coleman: training with these guys showed Sam what it took and inspired him.

On the surface, it looked like success. But behind every achievement was a body absorbing thousands of impacts, and a career that demanded more with every passing season. A body that took a beating until it broke and became stronger. Strength is the product of struggle.

The DESTRUCTION

WHEN EVERYTHING CAME TO A HAULT

Years of crashes, injuries, surgeries, and rehabilitation slowly changed everything. There came a point where the focus was no longer on competing, but simply on moving again.

Learning to walk wasn't something that happened once—it became a recurring reminder that the body has limits, and that true recovery is far more complicated than most people realize. Those years were frustrating, humbling, and often isolating. But they also sparked an obsession to understand why some people truly recover while others spend a lifetime managing pain.

The REBUILD

BUILT BACK STRONGER

After being knocked down and broken, rebuilding didn’t seem like an option. It was about becoming someone entirely different accepting he’d never do the things he did again - but knowing that he could pass it on to others

Sam had 30 years of pushing his body to the limits of human performance and Oxford education and development to reach the highest levels of my sport didn’t need to die.

The years spent learning, studying kinesiology, injury rehabilitation through personal experience, altered performance and the incredible ability of the human body to adapt when given the right environment and fuel gave him a unique set of tools which can be applied to almost any athlete at any stage of their own journey.

The second and third photos show him shirtless, before and after muscle build, with date labels from January and May 2017. The fourth photo shows him shirtless with a muscular physique, taken on May 2nd, 2017. The fifth photo shows him posing with a muscular build indoors, with tattoos visible, in a gym or home setting.

Every lesson was earned through experience or pain before it was ever taught to someone else. That journey eventually became AK37—a place where decades of fun and dedication, good and bad judgement, constant injuries and real-world experience come together with one purpose: helping others rebuild stronger than they ever thought possible, despite how bad you’ve been set back.

You can either deal with the pain you’re in or deal with the pain of change. This is the mindset we must adopt to crawl out of the gates of hell.

If you want it bad enough you’ll get it, if you don’t get it, you didn’t want it bad enough.”
