FLEX at a glance
Reviewers describe FLEX as a clean, well-equipped neighborhood gym with friendly staff and a non-intimidating atmosphere. Customers highlight the availability of various machines, reasonable pricing, and a diverse class schedule that includes options for different fitness levels. A recurring criticism notes that the circuit training area is often ignored by members, leading to conflicts over equipment usage.

Review from Google · view on GoogleI love this gym! Unfortunately it’s no longer functionally a circuit gym. In spite of the clear circuit and a literal bell that goes off every minute. No one uses it as a circuit gym and people will full on get in the next machine that you’re about to use with a straight look on their face.

Review from Google · view on GoogleI’m long past due for a review (sorry for gatekeeping) but Flex is the greatest neighborhood gym you could hope for. Clean facilities, friendly staff, well maintained machines, and a gorgeous and cool studio that’s open for use when classes aren’t taking place. Clientele is friendly, only positive vibes. No creeps, no intimidating gym bros, just people enjoying the space together as they reach their health and wellness goals. Rarely too busy. I’m not a class person, but the classes seem fun and diverse. Truly a gem of a gym and I feel so lucky to have it in my neighborhood.

Review from Google · view on GoogleI 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.
