I started in One arena in September 2025. The coaches are extremely patient and encouraging. The group classes are a great way to meet people and are less intimidating than going to the gym on your own. I already feel much more confident and now look forward to going each time. I would highly recommend this gym.
I’ve been training at One Arena for the past 4 months and it’s easily one of the best gym experiences I’ve had. The gym is always clean, well-organised, and fully equipped for all types of training. What really makes it stand out is the small class sizes — with a max of 8 people per class, you get a level of individual instruction that’s hard to find anywhere else. The trainers are attentive, knowledgeable, and genuinely focused on helping you improve your form and get the most out of every session. A big shoutout to the instructors — Gemma, Aoife, Darren, and Edward — who are all fantastic. They bring great energy to every class and make sure you’re supported while still being pushed to improve. There’s also a great sense of community, and the atmosphere is motivating without ever feeling intimidating. Whether you’re a beginner or more experienced, you feel supported and challenged at the same time. After 4 months, I’ve seen real progress in my strength and fitness, and I actually look forward to training. I’d highly recommend One Arena to anyone looking for a more personal, high-quality training experience.
I’ve been a member of One Arena Pouladuff for over a year now and can’t recommend them enough! The coaches are friendly, knowledgeable, and always happy to help. The team supported me through surgery by tailoring every workout so I could stay on track with my goals and remain part of the small group classes during my recovery. I’m amazed at the progress I’ve made in my strength and fitness lately—I definitely wouldn’t have achieved it without the One Arena team!
Fantastic small group gym. The coaches are incredibly friendly and supportive and the sessions are very well structured. You actually feel coached rather than ignored like in a big commercial gym. The atmosphere is welcoming and motivating and I’ve seen real progress since joining. Highly recommend to anyone looking to train properly.
One Arena is a brilliant small group personal training gym with equally amazing coaches and members alike. With their high-energy, welcoming environment, there's a place for everyone. You'll be supported and driven on by their skilled coaches to achieve your goals and better yourself!
