FLEX

FLEX FLEX offers 20+ exercise classes each week in addition to a private gym with a variety of popular machines and a 24 station circuit workout. Try us for free.

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

. For those into group exercise, FLEX offers over 30 classes weekly such as Indoor Cycling, Yoga, Pilates, Boxing, TRX, Barre, Zumba and more. And on Saturday mornings at 9am, members can take advantage of free boot camp in the park! Looking to fast track results, consider Personal Training. We offer the services of 4 certified trainers who can help you lose weight, build muscle, gain stamina or whatever your ambitious goals may be. Ask us for a free consultation. FLEX offers a casual, neighborhood vibe to suit the no nonsense fitness buff who just wants to get in a great workout, as well as the newbie looking for a friendly, easy entry point to getting in shape. Important Note: Classes and personal training are available to non-members as well as members of the gym.

The instructor, Marisa, will teach you skills to prepare your body before a fall ever happens. Through guided instruction and specific drills, you will learn how to regain balance when it’s disrupted and how to meet the ground safely when a fall can’t be avoided, reducing injury and building trust in yourself.
