This is what some of our clients are saying. 

Whether I’m gearing up for a big occasion, training for a race or just trying to stay healthy, fit and strong, I know I’m a better, happier person when I’ve been to No.17. The transformation to body and mind is unbeatable while the expert trainers are encouraging, knowledgeable and dedicated to help every client meet their individual goals.

The correlation between personal health and professional performance is now widely recognised. John Belton and No 17 have helped me hit my peak, address my stressors, and consider my wellness as a crucial part of my working day. I am fitter, faster and sharper because of them.
No. 17 has honestly changed my life. I’m going in to my 40s in the best shape I’ve ever been in. I’ve never felt so fit, and never eaten as healthily as I do now. And I really enjoy the unpredictability of Mark’s sessions.

Whether I’m preparing for a shoot, or just want to keep my fitness up while travelling, I love coming to Dublin because I get to work out with John Belton. He pushes me to do my best, mixing things up so I never know what’s coming next. Workouts are intense, very results-driven and enjoyable too.
— Millie Mackintosh
John’s holistic approach to wellness is an essential hallmark of what No. 17 offer their clients. He has a strong and loyal client base in Dublin, many of whom I have come to know well. He is a skilled operator who is reliable, punctual and an inspiration to all those he trains; I am fortunate to be one of those people. I have no hesitation in recommending John and No.17 to anyone who needs to focus on their fitness and wellbeing

Since I started I can honestly say I love going for my weekly sessions in your gym. It’s the first time ever that I’m starting to get noticeable results. The clean eating has really made a massive difference. Mark has been a great trainer & I would certainly recommend him to anybody. He pushes me hard but knows what I’m capable of and what my limits are. Also I never thought I’d say it but I actually kind of enjoy squats & lunges now that I’m doing them right!
