THE TEAM

FOUNDER & COACH

 Ed Kerry

I’m Ed Kerry, the owner and founder of GL52 Fitness, a gym built on passion, community, and real results. When I launched GL52 over three years ago, my goal was simple: to create an inclusive space where training is accessible to everyone, regardless of experience, lifestyle, or ability.

Fast forward to today, and I couldn’t be prouder of what we’ve achieved. GL52 has become more than just a gym—it’s a place where lives are transformed. We’ve helped members come off diabetes medication for the first time in over a decade, significantly reduce cholesterol levels, and embark on incredible weight loss journeys. Beyond health milestones, we’ve seen members push themselves to huge physical challenges, from conquering Kilimanjaro to competing in Hyrox events.

Something you might not know about me is that I’m an endurance athlete. In 2015, I completed the Marathon des Sables, finishing 21st overall out of 1,500 runners and as the 2nd Brit to cross the line. I’ve competed in numerous endurance races, constantly pushing my limits—just like I encourage our members to do.

As a highly qualified personal trainer, my drive is to make GL52 the best gym in Gloucestershire. I wanted to create a family-friendly, welcoming environment, where fitness fits into your life—not the other way around. As a parent myself, I know how important it is to have a space where you can train while knowing your child is safe, happy, and healthy.

GL52 isn’t just a gym—it’s a community, a support system, and a place where you can become the best version of yourself. Whether you’re looking for expert coaching, real accountability, or just a great place to train, we’re here to help you every step of the way.

Let’s keep pushing boundaries, achieving more, and proving that there truly are no limits.

COACH & PT

Jack Duncan

Hi, I’m Jack, a coach here at GL52 Fitness.

Fitness has always been a huge part of my life. I joined the Royal Marines at 16, where strength, endurance, and discipline became second nature. Alongside my training, I competed in football, MMA, and CrossFit, developing a passion for movement, performance, and pushing limits.

In 2016, I moved to Australia, where I earned my Personal Training qualifications and began coaching in 2019. Since then, I’ve had the privilege of working with incredible clients, helping them reach their goals and transform their lives. Seeing people progress, move better, feel stronger, and enjoy the process is what drives me every day.

My coaching philosophy is simple: perfect the fundamentals, move well, and train for longevity. I focus on technique, injury prevention, and building a solid foundation so you can train hard, stay healthy, and enjoy fitness for life.

Let’s get to work—see you on the gym floor!

Wow, just had my first sports massage with James and he was brilliant. From start to finish he was professional, polite and extremely personable. He located and resolved muscle issues I didn’t know I had. I floated out of the treatment room – feeling incredibly relaxed.
