Founder Story
Mainy's Journey
In 2019, Mainway Fitness found its new home in Unit 17/18, Tower Court. From the moment we first stepped inside, we knew it was the right place. With 5,000 square feet of open space, a large car park, excellent accessibility for local businesses, and the M4 just minutes away, it was the perfect canvas to build our vision.
The foundation and driving force behind Mainway Fitness has always been our award-winning classes. From being recognised as Wales' Best Group Training Facility to the success of our innovative BuggyBlast programme—designed to give mums the motivation to train with their babies alongside them—our classes have set us apart and become true game changers.
While we had every confidence in our group training, moving into Tower Court gave us a new challenge: creating a fully equipped gym floor. With state-of-the-art equipment and high-end kit, we were determined to offer our members the ultimate training experience—combining our renowned high-energy classes with a modern, functional training space.
The response exceeded our expectations. Very quickly, we saw not only amazing fitness results but also the growth of something even more powerful: a community. Members from across Llansamlet and the surrounding areas of Swansea came together, forming friendships, supporting each other, and building the welcoming, inclusive spirit that defines Mainway Fitness today.
We take pride in being more than just a gym. Our dedicated team and supportive members make new faces feel at home from the moment they walk in. It's this community-first approach that continues to drive our success.
Perhaps our biggest strength is our mindset—we never stand still. At Mainway Fitness, we are committed to continually learning, improving, and raising the standard of what a gym can be.
Our Philosophy
Our Philosophy is built from 3 core values:
Progress
We're very creative with our workouts and creating a friendly environment.
Results
We're very passionate about what we do and helping every single person that comes through our doors.
Community
We're very personal, we treat everybody the same making sure new and existing members feel welcome and supported throughout their fitness and health goals.
The gym has a very unique feel to it, I'm a local guy with a very close knit team around from family members to long life friends, which creates a very friendly atmosphere that is full of personality. I believe we have a perfect team – combined with a number of members that have been part of the journey from the start 2010 and who are still keen members hitting 10 classes every week.
"You really need to test this out and see for yourself, make the change today and we will change the way you think about training. We are passionate about what we do and our track record for transforming our members speaks for itself. We hope to see you very soon!"
