Literally just signed up today and I’m rating this facility strictly on my experience. I was in the hunt of a new gym since my gym closed.. The lady at the front desk was very kind and helpful, she answered all my questions and explained everything thoroughly. Which is major to me because I’ve been at facilities with very rude staff! I’m now ready to get back to it I will definitely be telling my friends about it here thank you!!! More...

I was going to another gym in town. They closed abruptly. A friend of mine said to try Underground. My only regret is I didn’t come over to Underground sooner. I was use to out of date equipment at my old gym. Everything here is touch screen and state of the art. It’s also SUPER CLEAN! More...
Nice environment. The other members are friendly. The staff is nice. Every time I visit they are cleaning the bathroom. So they are always clean. And I personally find grocery store and the laundry mat next door extremely convinent. Great Gym! More...

Totally Love this gym. It’s by far the cleanest gym I have ever been a member of. They have the best Zumba classes and all the equipment is brand new.

Great Gym with tons of parking. Attended other gyms in town and literally had to circle the block multiple times to try and locate a parking spot.

Best gym in the area. Very affordable, has all the weights and equipment I need, and it's the only 24 hour gym around here.
It’s open 24 hours. Has all the main machines you need. For the price for annual membership is worth it.
I'm not a member anymore due to medical issues. This place dosen't smell like a gym! The owner Shane is very personable and so are his employees. 24hr access with a card, lots of parking. More...
Best gym 24/7
Customer service could be a lil better, but the gym is great. Good atmosphere, lots of equipment and classes are always busy

I have been coming to this gym for years. The equipment is new and always in working order and if something breaks it's fixed right away. The staff is helpful and friendly. I love that it is 24 hours and having free tanning is an added bonus. I love their Zumba classes too. Best thing is that's it's always clean!! More...
These guys care about their business. They Will go the extra mile.
Great spot. Clean. Friendly Staff, open 24/7, overall great people and staff. Speaking of which..... time to renew my membership
Good gym. They have heavy stuff for me to pick up and put down, which is what I go for. I’d give them a 5 Star rating if they added 2 more squat racks.
Great gym. 24 hours. Clean.

Love this gym, but most of all love the fabulous class instructors. Lived in New York for most of my life and had been going to the gym for Zumba, strength training and other classes for years.

I belong to two gyms this one is a great deal with free tanning plus pleasant staff and is a gym for the in shape plus 24 hr access on top of clean locker rooms it's only missing towels and any type of soap or shampoo in the shower other then that it's great
Best gym in Stamford hands down! Staff is extremely friendly and knowledgeable. Lots of equipment and great classes offered with awesome instructors. The 24 hour access is great, don't ever have to worry about gym being closed. Very clean and always kept at a good temperature! If you're looking for a gym in Fairfield County this is the best one! More...
Best gym in Stamford. Very clean. Open 24 hours and a great staff. All the classes, weights, and machines you could ask for in a gym. The free tanning is a plus also. Very convenient location with plenty of parking. I recommend anyone looking, or even not looking, to sign up here. More...

Greta Accurso Yaeger
Great space, clean, bright , good music , beautiful locker/shower facilities.
Underground is easily the best gym in fairfield county. All of the equipment is brand new, the entire gym is extremely clean, and everyone that works there is really friendly. I tried a few other gyms in the area before finding underground, and would never go back anywhere else. The free classes are also amazing! More...
I cannot say enough good things about Underground Fitness. I moved to Stamford about four years ago and was looking for an affordable, clean, well maintained gym with a variety of group class options in order to get ready for my upcoming wedding. I was also interested in exploring personal training. The staff couldn't have been nicer, and Shane was able to find me a personal trainer best suited to my needs and budget whom I still work with to this day! More...
I researched a lot of gyms before deciding on Underground Fitness. It was an easy choice after touring this facility. The equipment is top of the line and there are lots to choose from. I love how clean it is there, that is so important to me. The classes are awesome and the free tanning is great. Best of all, it's always open! More...
I loved my experience at Underground Fitness. It is a clean workout facility and the equipment is in good shape. Shane was especially helpful when signing me up and when I had to cancel my membership due to moving out of the state. Shane did all he could to make my experiences better and I am sorry I am no longer in the area to use the gym. More...
My former gym was closed for every snow storm. So when i heard Underground was open 24 hours and did not close during the storms, I dropped my old gym and joined on the spot. Now i know i will always be able to get my work out in!!!!!! More...
I am new to the area and when I visited Underground Fitness for a tour, I decided to sign up right away. The facility is extremely clean, staff is very friendly, equipment is new and I always find what I need for my workouts. I could not be happier with my decision to join this fitness club. More...
Just graduated college and moved to the area to start my new job. I was pleasantly surprised with the high-end feel of the gym. Definitely worth the money.
Great gym. It's a great space, with a lot of different equipment. Has a high energy vibe that's good for a workout.
I absolutely love this gym! Its clean and organized and the staff is extremely helpful and friendly. The 24 hour access makes my super busy schedule so much easier because I can go whenever I want. The staff is always available to answer questions and they have excellent classes and traniers for those that need that extra push, which are all included in your membership. The instructors of body pump, zumba, pilates, spin etc are amazing and every class is a great work out. They have a great variety of machines and numerous of each one. I tell everyone I know about this gym and have bought lots of friends and family over - they are just as happy!! They also offer a 3 day trial pass for those that want to try it out first and of course free tanning beds for those that are interested. If your looking for a local gym - theres no better option then Underground!! More...
