I started working with Dylan with the goal of building lean muscle mass. It's been about 4 months and I have lost around 10lbs while gaining around 2-3 lbs of lean muscle mass.Every set of every workout is dialled in and I feel I am working out at a peak level without feeling over stressed or strained.The combination of Dylan's knowledge, coaching style and the niche equipment in his gym is a potent combination that's giving me great results.The workouts themselves are fun and the vibe in the gym with the other members is welcoming and easy going.It's been fun so far and I look forward to continuing my fitness journey with Dylan!

Great gym, the best equipment in town, great people, and even better coaching. I’ve been really happy working with Dylan. It’s easy to stay consistent when you enjoy where you’re working out.

Have been training with Dylan 7 months now and it’s been great - top tier machines, really helpful coaching, and constant progress being made. It’s a fun group of people in this gym but never so busy to be disruptive. Pricing works out to be pretty affordable vs other 1:1 training gyms I looked into.

Dylan Thomas is an elite trainer/coach. He has a complete understanding of how to get results. Every details matters to him. His facility is super clean, large, and has the best equipment that he’s hand selected and refurbished. It’s a privilege to work out here. Zero nonsense.

I’ve enjoyed my time at ÜAC, it is the most consistent I’ve ever been following a program specifically designed to my health needs and exercise evolution. Coaching has helped me remain accountable which has given me significant results. No nonsense, worth the investment.

Amazing training facility. The gym is exceptionally well equipped with everything needed for effective workouts and never feels crowded or busy. Programs are challenging, motivating, and tailored to individual goals to deliver real results. Dylan is always helpful and responsive to questions. Highly recommended for anyone looking for knowledgeable and professional coaching.

Unterground Athletic Club is, square foot for square foot, one of the best-equipped training facilities I’ve ever been in. The atmosphere is welcoming yet focused, built for serious training at any level.What truly sets it apart is the coaching. The facility is home to highly knowledgeable, experienced trainers who create a constant environment of learning and improvement.If you want a gym that prioritizes quality, performance, and expertise, Underground Athletic Club is hard to beat.

I've been training here for 5 years almost and I have really never looked back! Dylan has pushed me and made me so much stronger than I ever thought I could be. He is very knowledgeable and helps you work towards your goals. I don't see me ever stopping!

I've been really enjoying working with Dylan. He's professional, friendly, and incredibly knowledgeable.What I appreciate most is that he takes the time to explain the purpose behind each exercise, which has helped me better understand my training and stay motivated even when the motivation isn't there lol.His expertise has been a big part of the progress I've made. I would highly recommend him to anyone looking for a knowledgeable, friendly and supportive trainer.

I have been training with Dylan Thomas since 2021. He is by far the best personal trainer in Toronto and his gym the UAC is the best gym in the city. Training at UAC has been transformational for my health and fitness journey. I have gained strength and completely changed my body composition. Not to mention the state of the art equipment! Dylan curates the gym to push clients to their max for the best results. I cannot recommend joining UAC and training with Dylan enough!

Best of the best equipment.great ppl.clean and great trainers

I started training with Dylan 4 months ago, twice a week. The focus has been on body composition. My confidence has never been higher, I look and feel great. My clothes fit perfectly. I'm a client for life.

Highly recommend this state-of-the-art facility for people focused on getting in shape. Equipment is unique and well curated. If you have the opportunity to train with Dylan and put in the work, you’re guaranteed to get results that will speak for themselves.

Great private gym in Leslieville which has all the equipment you could ever need. I’ve had multiple different training goals from post-surgery rehab to hypertrophy for rugby and UAC has always been able to provide the tools to help me meet and exceed these goals.As a bonus, Dylan and the other members are always a good laugh to train with and around.

I’ve been training with dylan at UAC for almost five years, and I honestly can’t recommend him enough. We trained in person for the first few years before transitioning to online coaching, and the level of support, accountability, and attention to detail has been just as strong virtually as it was in the gym.He’s helped completely transform my body, but more importantly, he’s helped transform my confidence. What sets him apart is that he understands fitness isn’t just about following a program—it’s about building something sustainable.A few years ago, I suffered a serious injury that required months of rehabilitation. It would have been easy to lose all the momentum I’d built, but he took the time to understand my recovery, worked around my limitations, and adjusted my training so I could keep making progress safely.Another thing that really sets this gym apart is the equipment. The quality and variety of the machines are unlike anything I’ve experienced elsewhere. Many of them offer incredibly precise adjustments, allowing you to fine-tune your positioning and train muscles from different angles with much greater control. It’s clear that a lot of thought has gone into selecting equipment that supports both performance and injury prevention. Whether you’re focused on building muscle, improving strength, or recovering from an injury, having access to this level of equipment makes a noticeable difference in your training.

Dylan is a great trainer and has helped me meet my fitness goals. The space, UAC is a fantastic private gym. They have the best equipment and is a great judgement free zone.

Awesome gym! Dylan is a very knowledgeable trainer, and has filled his gym with an impressive collection of equipment, all of which is maintained better than any gym I've seen.

I’ve been training with Dylan here and can’t recommend him and the gym enough. Dylan is an incredible trainer. He’s super attentive, knows exactly how to push you, and understands your limits and any previous injuries without judgment. The results I’ve seen have been amazing.The gym itself is fantastic! It has equipment I’ve never used before that has made a real difference in my training. It’s always clean, never overly busy, and I’ve never had to wait for equipment. The community is incredible too. Everyone is friendly and welcoming, which makes it an even better place to train.

Great gym with top-tier equipment and a really good atmosphere. Everything is well maintained, and it’s a great place to train.I’ve been training with Dylan for the last 8 months and have had a great experience. The sessions are always a good time, and he has really helped me on my fitness journey. I’d definitely recommend this gym to anyone looking for a quality place to train.

I’ve been training with Dylan for a while now and it’s been a fantastic experience. The gym has excellent equipment, a welcoming, friendly atmosphere, and Dylan is a knowledgeable trainer who genuinely cares about helping you improve. He knows exactly when to push you outside your comfort zone—and yes, he can be a bit of a D sometimes—but it’s always for your own good. If you’re looking for someone who will keep you accountable and help you get real results, I’d highly recommend training at Unterground!

You know you've found the right gym when the owner is relentless in pursuing the best equipment and is as passionate about your programming. I'm even enjoying leg days...

Amazing gym with an incredibly welcoming atmosphere! The coaches are knowledgeable and genuinely invested in helping you reach your goals. The facility is thoughtfully curated and well-equipped, and has such a great community. Whether you're new to working out or have years of experience, this is a fantastic place to train. Highly recommend!

Best gym in Toronto, top of the line machines and equipment that you can’t find at any other gyms downtown

I’ve been training with Dylan since 2021, and the transformation has been incredible. I’ve built more muscle, achieved the best definition of my life, and gained a level of knowledge about training, nutrition, and overall health that I never would have on my own.On top of that, Unterground Athletic Club is one of the best gyms I’ve trained at. Every piece of equipment has been carefully selected, creating a curated training environment that prioritizes effective workouts and real results over simply filling the floor with machines.Dylan genuinely cares about his clients, keeps you accountable, and knows how to get the best out of you. If you’re serious about achieving lasting results, I couldn’t recommend Dylan and Unterground Athletic Club more highly. 💪
