Flex is a great place for all the reasons I have not liked gyms. It is smaller than most , which i really love..never crowded at the times I opt to go, it is clean, staff is very nice also. Flex is also affordable for those of us who are now retired and live on fixed incomes but want to stay active and healthy. Best of all..Flex is conveniently located right in my neighborhood. Just love my Flex Gym.

Flex is a great, no frills, neighborhood gym. The space is much roomier than it looks from the outside with a studio, spin room, and weight room in the back. The weight room has two squat racks so there is rarely a line. It is clean, the people are nice, and it's usually not crowded. What more could you ask for? I hope Flex gets to re-open soon!

This is a great neighborhood gym. The staff is always friendly and helpful; the equipment is well maintained. Whether you want to do circuit training, free weights or take one of many classes, this is the place to come. Just a real great environment to work out in.

After not attending a gym in over a year and a half, I was very nervous about coming back - partially due to health and safety but mostly because gyms can be intimidating places! Not so at FLEX, the atmosphere is warm and welcoming and staff/patrons are very helpful & friendly. It feels good to be back!

Great gym, highly recommended. Staff is friendly, accommodating and responsive. Equipment is always in working order. Facility and equipment is always clean. Numerous exercise and yoga classes for people of all ages, interests and abilities. I’m giving 5 stars but have one complaint/warning for those looking for a circuit gym. Circuit etiquette is not enforced here. You will encounter people who are oblivious to circuit etiquette. They jump from machine to machine without regard to whom might be looking to use it when the bell rings. So you may find your circuit interrupted by a clueless member. Early mornings see the place filled with predominantly elderly women who use Flex to sit on the equipment and socialize with each other while ignoring the circuit bell. Mildly frustrating when you’re pressed for time in the morning. That said, overall I love this gym and would recommend it to anyone looking to get in shape.

I tried Flex on a free 3 day pass. I want to join Flex Gym again because it is located so close to where I live. Note:: The problem with the Stair Master machines in general is that the rise is too high and that makes me not want to exercise on it very long, even on a slower setting and I love walking or running up a flight of stairs. Most stairs are 6" high, whereas the Stair Master step height seems like it is 9" or 10." I want to forward this comment onto the maker of Stair Master and see if I get a response because all the gyms seem to have the same step rise.

While a small gym, it never feels crowded enough to where you can't do your workout. It's a clean and organized space. There's enough room, weights, and machines to accomodate your level and type of work out for the day. The gym does a great job of fostering a collaborative environment as other members seem to care about etiquette like not hogging an area or weights for too long.

100!! Well-equipped, clean, convenient boutique gym that's not overcrowded, with good customer service, great instructors and friendly community vibe too. One of the few gyms with Open gym option, as well as classes that's very reasonably priced. Having been to over 10 gyms in 3 different countries, and joined an Equinox-equivalent for 4 years, I can honestly say this is one of the decent ones given its price point. Really glad to have this in the neighborhood.

This gym is an excellent place. It is clean, nice environment, good taste in workout music, excellent instructors, the classes are fun and versatile, great workout machines and friendly staff. I really enjoyed my time there!. If I still lived near by the piedmont ave. I could go to flex again without any doubts. Believe me, I'm a gym bug and this is the best place where I've workout by far! Thank you Flex, George and Bruce and all the staff there for being so attentive to costumers, you really take care of us!

Great value for a basic membership. It’s clean, has good equipment and good hours. We haven’t taken the classes but I hear they are good.
