The instructors at Nitroflex are amazing, everyone is super friendly and welcoming. They offer a great range of classes and the locker rooms and gym are always clean and well-kept.

I'm really happy with this gym! The environment is great, the classes are top-notch, the instructors and staff are professional and welcoming, and it's always clean. Plus, it seems like they're constantly making improvements. I'm glad you all opened this place up. Thanks!

There is no other gym in the area that can compare to Nitroflex because of its spa offerings, abundant classes, machine & cardio variety, and now the cafe menu.

I would definitely recommend Nitroflex to anyone looking for a gym in the area! The facility is beautiful and clean, the equipment is great, the classes are excellent, and the staff and trainers are so friendly and knowledgeable! Come check it out!

I love spin bikes! They are so different from anything else I've seen and they make spin class so much more fun! I'm also loving Pilates with Connie and Cathy. They are both great personal trainers who are really helping me improve my fitness!

I love this gym because it's full of people working hard to improve their health and fitness levels. The staff are always friendly and welcoming, and the owner is great!

Fantastic experience: I’ve recently joined this gym, and have really enjoyed it. They offer plenty of classes, which aren’t always my cup of tea, but my wife enjoys those! Machines are up-to-date, and while the place is busy, it’s never really crowded. Wait times are nearly non-existent. Great gym, run by some very nice people!

Fantastic experience: This is a great place to work out no matter your fitness level as there is something for everyone. Stretching, yoga, Pilates and a host of high intensity classes. What I like about it is I can do something different everyday, and on most days can take 2 or even 3 classes that incorporate, stretching, fitness and then core exercise classes. Recently, they added a strength component to their spin and row classes making them more of an interval workout which combine a higher heart rate with lifting weights. The classes are high tech, incorporating a computer screen to keep you on track, they are never the same, the music is great, and the instructors are approachable, motivating and very knowledgeable.

Fantastic experience: I’ve been a member of Nitroflex since another Chester gym closed several years ago. Other nearby gyms were disappointing for a variety of reasons. I continued to hope that a new, first class gym would open to replace my original gym. Thankfully, Nitroflex appeared and is that terrific facility that I had hoped for. Large, airy, great equipment, friendly people. It fits the bill for me perfectly. Great place!

Fantastic experience: Joined this gym a few months ago and I love it SO much. They offer such a variety of classes every day with incredible instructors. Heather and Shannon are especially the best instructors who learn everyone’s names and make sure you’re working out to your fullest potential. I’ve onky had wonderful experiences here. This gym is 25 mins from me, I have about 20 closer gyms I could be going to but THIS is the one I choose (:

Positive experience: Only issues is how long it takes to use the free weights. After everyone is done talking and on the phone you might be able to get on the machine you need.

Fantastic experience: Great place to workout. The staff is friendly. Equipment is clean and always in working order. The bathrooms and locker room are clean. They have cryotherapy if you want to try something new. There is child care for those who need it. A great gym located in the ShopRite place on Route 206. The easiest spots to park are in the rear of the mall.
