- When I started in this gym over a month ago now, I was very eager and always had a great interest in the gym but found it hard to have the confidence to go. All the staff members here have been beyond unbelievable.
Denis17 May 2024Excellent gym- would highly recommend anyone looking to kickstart their fitness journey to try One Arena. I have had impressive results in just a few weeks
Colm Murphy1 May 2024Well organised, professional and friendly instructors. Good variety of workouts.
Alice Murray23 March 2024Loving my fitness journey and lifestyle change since joining one arena. Big shout out to the trainers in the passage gym 👍
Christ Koffi13 March 2024One Arena Is a fantastic and beautiful facility that welcomes all members with open arms whether they are experienced gym user or new beginners. I would highly recommend for all enthusiastic gyms users to visit OneArena for a few sessions.👍🏾
Ber O brien13 March 2024Having never stepped foot inside a gym I joined One Arena (passage west) in September 23 and walked in their doors full of self doubt, that was changed in my assessment with Gemma who encouraged me to sign up to a six week program and take it from there, today I find myself stronger, fitter and very capable. If you are looking for a gym that is committed to your success (one arena’s line) give them a call as age and capability are not a barrier here, I cannot speak highly enough of all the trainers I have met and looking forward to seeing what else they can drive me to achieving in the future.
Sophie O' Brien29 February 2024When I started in this gym over a month ago now, I was very eager and always had a great interest in the gym but found it hard to have the confidence to go. All the staff members here have been beyond unbelievable. I was able to have private conversations discussing where I was at with my progress, in terms of diet and exercise. Everyone is extremely welcoming and friendly making the classes a really enjoyable experience. There is a great variety in classes and they also get changed up every month. I would highly recommend this gym to anyone looking to start up!
