The workouts are always different and the class truly flies by. The crowd is always mixed and has a great overall energy. The staff is extremely welcoming. Mike is a truly a fantastic coach. Parking is easy and the facility is clean and intimate. I've done just about every fitness class and discipline imaginable and can honestly say that New York Underground Fitness should be in everyone's workout routine!

The instructors are truly exceptional. They are extremely friendly and welcoming: From the day I started, they've called me by name (they even pronounce it correctly). They encourage and challenge people of all fitness levels who are as excited as you. Moreover, they assist switching weights, sanitizing the stations, and correcting your form.

This gym is an absolutely GEM in the heart of NYC. I'm beyond thrilled to have discovered it through a PT client. Great for trainers and workout buffs alike, with ALL the necessary equipment for dynamic workouts (free weights, cardio machines, strength machines, cables, bands, ropes, mats, balls, etc.) for an actually affordable price!! It's almost too good to be true!!

Fantastic gym that is stacked with weights and machines. The vibe is amazing and there are lots of very learned trainers that you can work with to transform your body. I highly recommend it!

Diamond in the rough - Excellent clean gym with everything you need to get in and get out. That includes bench, heavy free weights, squat rack, Stairmaster and more. As a frequent traveler to NYC, this was a tremendous find and I will be back. Thanks for everything.

The gym is so far the best in town. It is packed with vibrance that drives you work out at your level over the limit.

Great little gem of a gym (see what I did there?). Owner is a genuinely nice guy. Great for lifters looking for a short-term gym for some squats, deadlifts, and benching (only one cage and one bench--with safeties--though).

Great gym! It's the Cheers of gyms - where everybody knows your name. It's not pretentious and never overcrowded. Highly recommended.

To say that this is my favorite gym in NYC would be an understatement. The location, the ambience, the equipment, and the trainers are all top notch. Highly recommend!

One of the best gyms I've ever been too! It has all the equipment you need plus it is in great condition - always clean and organized. Additionally, the owner, Eric, and all personal trainers are very friendly and knowledgeable in the topics of fitness and healthy eating. Definitely recommend this gym to everyone!

Comfortably sized gym with a great atmosphere! It has all the equipment you need to get a complete workout, and the staff is very knowledgeable, welcoming, and helpful. Love this place!

I want to simply say, this is one of the best gyms I have ever had the pleasure using.
The owner Eric Slayton, is a pleasure to be around. The personal trainers are actually training and not on there cell phones. And it has nearly all equipment u need. From 1st time visitor to Bodybuilder. My only complaint is I did not know about the gym my previous 50 + visits to NYC. If you are anywhere near Hell's Kitchen. And need a gym to meet your needs, UNDERGROUND FITNESS is the gym for u!!

Offers all the equipment one needs to get a great workout. A very pleasant surprise when staying at the holiday inn midtown. Was never over crowded and staff is very pleasant. Strongly recommend in midtown area.
