FLEX.... When we opened our doors in 2010, FLEX offered the area's most challenging circuit workout, but now with our recent expansion FLEX is a mecca for people who like to get their workout on in every imaginable way. In addition to our 24 station circuit workout, we now offer a spacious functional training / free weight area for members to do their own workouts and a fully loaded cardio room
