Belinda Marie CreeTrustindex verifies that the original source of the review is Google. Great programmes, fantastic coaches, nice facilities 👍🏻 Stuart McCartanTrustindex verifies that the original source of the review is Google. Best gym I’ve been to so far. I was reluctant to try Core at the start as I was used to training on my own or with a friend. I was amazed at how much I enjoyed the classes/programs. Such a friendly welcome from the staff and members. They cater for all needs. If you can’t do one of the exercises in the class due to injury, disability etc they will find you a different one to do as part of the circuit. Most people adapt something so you don’t feel embarrassed in any way. The staff are always on hand to give tips and correct technique where needed. Well worth the money. I haven’t looked back since! Louise HopkinsTrustindex verifies that the original source of the review is Google. Core fitness NI is such a welcoming gym. I’ve always felt self conscious in a gym but core is very different, Everyone is so welcoming. Anything you need to know there is always someone there to help you out! I would definitely recommend Core Fitness NI Charlotte BellTrustindex verifies that the original source of the review is Google. A great gym with an even better community! Going to a new gym can feel daunting but was made to feel welcome on day one. Coaches are knowledgeable, motivating and supportive all whilst making it enjoyable! Would highly recommend! Vanessa MannisTrustindex verifies that the original source of the review is Google. I have been a member of Core Fitness NI for over 2 years now. I have tried many gyms before but never stayed long term. The coaches are all very friendly ,knowledgeable and help you achieve your goals whilst pushing you out of your comfort zone. Always great craic and good vibes , I have just finished the Fusion course and feeling stronger than ever 💪 Highly recommend Core Fitness NI , give it a try you won't regret it . Gareth LowTrustindex verifies that the original source of the review is Google. Core is like no other gym, I have tried so many other places & not only does Core get the results I want but they make it so much fun on the way I really can’t recommend Core enough Ruth JustinTrustindex verifies that the original source of the review is Google. Core fitness NI is a fab space and gym. The team are so keen to help and always willing to progress you on your fitness journey. You will make new friends as an added bonus and get some laughs along the way. The team are so friendly and will make you feel at ease. The equipment is modern and they are always adding new items to keep it fresh. Fab place to work out. Cara DonkinTrustindex verifies that the original source of the review is Google. I joined core Fitness in March 2023.. starting with bootcamp then started 6 pm transformation. Once the results started showing I combined strength and transformation. The coaches really are the best. Know your strengths & weaknesses and push you to the limits to achieve your goals.. Core for me is to achieve my target strength and gains now 💪 but with the trainers, members and the friends in any class you attend it's the only place I want to be after work ... hard work, consistency and the best craic (usually at my expense) lol.. 💯 core is my happy place . Especially 3 strength classes 6 pm and sat morning 😁 I have never been at a gym where you can't wait for your next session. Instead of making excuses or dreading. . From bootcamps to strength... 2 hyrox sims and now running 3 times a week.. definitely recommend the best gym ever. Im a different person now. Mentally and physically. Can't thank these guys enough for how far I've come.. more to come #2025 goals 🙌 Mark ArnoldTrustindex verifies that the original source of the review is Google. I've been training at Core Fitness NI for several months now, and the impact on my life has been extraordinary. The tailored fitness programs have not only significantly improved my strength but also boosted my confidence. I've shed several kilograms, feeling fitter and healthier than ever. The atmosphere at Core Fitness NI is incredibly welcoming and supportive. The staff genuinely care about your progress and are always on hand with advice and encouragement. The friendly environment makes every session something to look forward to. If you're looking for a fitness journey that delivers real results with a team that genuinely cares, Core Fitness NI is the place to be.
