Great to work with experienced trainers who customize their program uniquely around the needs of their clients.

Id like to recommend this gym to everyone. This is the perfect way to improve your physical and emotional fitness. Theyd brought a specialist mentor with them. Excellent for first-timers.

The instructors are truly exceptional. They are extremely friendly and welcoming: From the day I started, theyve 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.

Fantastic gym!

This gym is an absolutely GEM in the heart of NYC. Im 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!! Its almost too good to be true!!

One of the best gyms Ive 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!

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.

Great selection of weights and equipment available. Clean gym with good staff

If you are concerned about your fitness and want to join a gym with all good equipments then trythis gym. You will not be disappointed.

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.

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).

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!

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

I was very thorough in going around checking out the various fitness clubs in the midtown/west side area. Once I found this place, it was a no-brainer: all the equipment one could need; a serious atmosphere, but still fun and chill; easily the best price. The overall value earns it 5 stars.

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.

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 Hells Kitchen. And need a gym to meet your needs, UNDERGROUND FITNESS is the gym for u!!

Small but great gym for all levels. Staff and owner are very friendly

I stayed at the Holiday Inn Midtown on 440 W 57th street for an extended weekend.I had brought with me some gym clothes as I had read there was a fitness centre on site at the hotel.Fearing your typical hotel fitness room, I ventured down to the basement where the fitness centre is located.To my great joy and amazement, I discovered this fantastic basement gym.This is a serious gym, with all the equipment you need for a good workout. There are plenty of treadmills and ellipticals for the cardio bunnies (I suspect most of those who used them while I was there were hotel guests).There are plenty of dumbbells and a few benches for free weight exercises, plenty of kettlebells, one squat rack, a smith machine, a cable rack, leg press, hack slide, to mention a few.The gym is clean, tidy and although the music played wasnt to my liking (being a metalhead), the volume was low and wasnt a nuisance.I spoke with the morning manager while I was there, and he was very friendly and seemed like a good guy,Highly recommended.

I love this gym!

Clean

The best fitness center outside my home (Vienna) where I ever was. Great atmosphere, great equipment and a great crowd. The owner is totally friendly, and there is a good togetherness in a real old school atmosphere, yet with top equipment. During my vacation I trained there 4x and was thrilled every time.

I really like sports
