Our History
Originally, “Onslow Spa” opened with just a 4,200 sq ft facility and featured the only steam room, sauna and whirlpool in the area. The spa included a small workout area of six stations, one universal, two manual treadmills (electric treadmills had not be invented yet) and five stationary bikes. Our Jacksonville gym offered very limited aerobic classes and childcare.

Back then, men and women did not work out together, so there were alternating days. In the mid 80’s we introduced co-ed workouts on Saturday nights, and gradually expanded to a full time co-ed facility.

We added the only indoor heated pool in June of 1982 and a second whirlpool. Then rapidly expanded our workout floor, added a large group fitness studio and enlarged the kids club.
