EXCELLENT Based on 393 reviews Posted on James GunnTrustindex verifies that the original source of the review is Google. Joined Underground Fitness after several recommendations. Delighted with the progress to date. It is great having an instructor present to show you proper technique. It has been many years since I was inside a gym, yet the importance is huge, especially as I age.Posted on Rachel KingstonTrustindex verifies that the original source of the review is Google. Brilliant classes and quality trainers who push you in every class so you get the most out of each and every sessionPosted on James CulliganTrustindex verifies that the original source of the review is Google. Great gym, good trainers, nice facilities and class atmosphere!Posted on Kate BarrettTrustindex verifies that the original source of the review is Google. I had been a member of Underground Fitness since the end of 2023. Underground Fitness is a great sized gym for group training, with everything you need at your own rack, and medium sized group training. Whether it’s your first time weight training or you’re familiar, the coaches are there to answer questions and keep you on track during your session. The classes schedule is really great, with later evening classes and Saturdays for those who have difficult schedules. Patrick (the boss) is really great for check ins and helping you meet the type of training that works for you.Posted on april joy sawitTrustindex verifies that the original source of the review is Google. Great gym! Really clean 👌 Amazing place to work out. The staff/PT are friendly, knowledgeable and helpful. Classes are both challenging and fun and the atmosphere's really friendly. (You should add kickboxing on Wednesdays or Thursdays too, just saying 😉) it's all good anyway!Posted on Brody Monkey HodginsTrustindex verifies that the original source of the review is Google. You simply won't get the quailty and quantity of what's on offer for a fair price anywhere else. One stop shop for fitness and healthPosted on Solar ClarityTrustindex verifies that the original source of the review is Google. Great setup with personal attention. Looking forward to the next 6 weeks.Posted on Célio LaraTrustindex verifies that the original source of the review is Google. This is the first time in my life that I actually enjoy going to the gym. Since I started training at Underground Fitness, I’ve discovered that it’s possible to have a real balance between the gym and my personal life. I feel constantly motivated because the training style is different from a traditional gym. Having my own box and a different routine every day of the week keeps the sessions interesting and never boring. The instructors are extremely attentive and caring. For example, I have a knee issue, and they always adapt the exercises so I can train safely while still strengthening the muscles needed to improve my condition. I usually train early in the morning, and I highly recommend training with Niamh, Niall, and Stephen.Posted on Luke STrustindex verifies that the original source of the review is Google. I joined Underground Fitness 5 months ago, and it has completely transformed my approach to fitness. From the moment I walked in, the atmosphere was incredibly welcoming and motivating. It's not one of those intimidating gyms; there's a real sense of community here. The coaches are phenomenal, they're knowledgeable, approachable, and genuinely invested in helping you achieve your goals. They take the time to correct your form and push you to be your best in a safe and supportive way. The equipment is top-notch and always well-maintained, with a great variety for any type of workout. In just 5 months, I've seen more progress than I did in years at other gyms. I'm stronger, more confident, and actually look forward to my workouts. If you're on the fence, take the leap. You won't regret it. Highly, highly recommendPosted on Piia SchroderusTrustindex verifies that the original source of the review is Google. Super gym, classes and instructors, with the bonus of yoga classes and sauna in the same premises.
