About Us

Spark Gym started in Walton-on-the-Naze in 2020 with a simple idea: build the kind of gym we would want to train in ourselves.

Since then, Spark has grown to two 24/7 locations, with Clacton-on-Sea opening in 2025 and doubling in size just one year later.

We remain proudly independent, continually investing in our gyms, our equipment and the people who train with us.

Spark Gym is independently owned and run by people who genuinely care about the gyms, the equipment and the community we’ve built.

Meet the team behind Spark Gym — from the people who started it to those who help keep both locations running every day.

Jamie Fuller and Jamie Hearn are the owners and co-founders of Spark Gym, launching the original Walton-on-the-Naze gym in 2020.

Since then, they’ve grown Spark into two 24/7 locations, with a focus on serious training, quality equipment and continually improving both gyms for their members.

Lewis is our Head Personal Trainer and a key part of the Spark Gym team. An ex-Royal Marine, he brings experience, discipline and a straightforward approach to training.

With years of hands-on experience, Lewis helps members of all abilities train effectively, build confidence and make lasting progress.

Jo is our Head of Cleaning & Hygiene and plays a huge part in keeping both Spark Gym locations clean, welcoming and running to the standard we expect.

Her attention to detail and commitment behind the scenes help make sure members have the best possible environment to train in every day.
