FOUNDER & FITNESS COACH

ED KERRY

About me

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

About me

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!

FIRST, WE UNDERSTAND YOU

Your goals matter to us. Whether you’re looking to lose weight, build strength, or master a new skill, we’re here to fully support and embrace your journey. From day one, we’ll pair you with a knowledgeable coach who’s best suited to your needs, ensuring you have the guidance, expertise, and encouragement to achieve far more than you ever thought possible. Together, we’ll create a clear path to success—tailored to you.

THEN, THE FUN BEGINS

Now comes the best part: training. Your coach will be there to motivate, challenge, and support you every step of the way, keeping you accountable and inspired to push past limits. We’ll progressively increase the intensity of your training, making sure you’re always improving, never plateauing.

We also know that life happens—progress isn’t always linear, and goals can evolve. That’s why our approach is flexible and adaptable, ensuring your training remains effective, enjoyable, and aligned with your ever-changing journey.

Whatever your starting point, we’re here to help you go further than you ever imagined.

What does GL52’s personal training include?

With over 15,000 hours of hands-on experience, Ed has seen first-hand that the traditional “60-minute trainer” model is one of the biggest wastes of time and investment. True progress doesn’t happen in just an hour—it happens every day, through consistent support, accountability, and structured guidance.

That’s why Ed has developed a seven-day coaching approach, ensuring you receive ongoing accountability, expert guidance, and the tools needed for long-term success. This method not only delivers real, lasting results but also creates a commitment between both you and your coach, setting you up for progress that extends far beyond the gym floor.

This ethos of full-circle coaching has been instilled in every trainer at GL52, making our coaching experience truly unique—something you won’t find anywhere else in Gloucestershire.

Consultation

Every great story has a beginning, middle and end. The consultation is the best part of the process, we get that nervous excitement like we do when we start a book. In chapter one we will get to know one another and go over some history of health and wellbeing, discuss goals and targets you may have and come up with a plan to achieve these and more.

Nutrition

Every goal will have a physical element to it but alone this will not lead to success, your diet is a huge part of who you are and where all your energy balance will come from. At GL52 we don’t leave this to chance and we will work with you on a personal level to make sure you eat well and the daily eating is in line with your goals.

Practical Sessions

Training here at GL52 is both fun and informative at the same time. The clue is in the title ‘Personal Training’ we make it personal and bring an empathetic and respectful approach to your sessions. These wont fit just anyone, they will be just for you and your targets.

Recovery

Being fresh and ready for your next training session is so important for muscle repair and general health and wellbeing. We will work on your sleep patterns and give guidance to improve these areas to help make sure you have everything you need to lead a healthier and successful life.
