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 I was use to out of date equipment at my old gym.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...

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. The lockers rooms are very modern and immaculate. My favorite feature is all the peloton bikes they have, allowing me to take classes anytime I want. Great value! More...

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 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 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...
