Our 14,000 square foot Jacksonville gym is dedicated to making fitness accessible for every member — youths and seniors, moms and elite athletes alike under one roof — and helping them achieve their fitness goals.

Originally, “Onslow Spa” opened in 1981 featured the only steam room, sauna and whirlpool in the area. A broad range of strength, cardio, circuit, and functional training. In 1982, the pool was added and to this day, we have the only heated indoor saltwater pool in Jacksonville, NC.

Over our 39+ year history, our gym in Jacksonville has maintained the same ownership and management, while continuing to evolve with the changing needs of our members, upgrading not only the physical facility itself but the programs we offer. Our gym is set apart from the others with our comfortable, family-type atmosphere and upscale amenities available to all our members.

In September of 2018, Onslow Fitness was hit hard by Hurricane Florence and the damage was devastating. Rather than throw in the towel, we decided to turn tragedy into opportunity and completely renovate the facility. The newly remodeled club opened in December, 2018 with a new expanded fitness floor with improved layout, new equipment in the weight room and the cardio area, added turf area for stretching/kettlebell workouts/training access, new flooring club-wide including state-of-the-art fitness floor, a completely remodeled childcare room and last but not least a locker room remodel/update.

Onslow Fitness completely remodeled and renovated the entire facility in 2018 after Hurrican Florence, continuing to serve the fitness community of Jacksonville.


"I love the workout environment. I feel motivated and love all the many options available such as cardio equipment, TRX, personal training, classes, free weights, and a swimming pool. Absolutely everything you need for a challenging workout. The staff is amazing and I’ve met some wonderful people."

"I love Onslow [Fitness]... The equipment is great and it is not too crowded, it seems they have found a way to space things pretty well. I also love that it is available 24 hours. The daycare is wonderful and I love the video screen showing you the daycare where they don't know your watching. Creates a secure feeling. Great place to be!"

"My family and I have been members of Onslow Fitness for 2+ years now. I have to say it is a great gym. The environment is welcoming and upbeat. The staff is always friendly and open to giving advice to anyone who seeks it. The gym facility itself offers practically anything you would want in a gym environment. Overall I'd recommend OF to anyone! It has something for people of all fitness levels. If you aren't sold yet by the reviews from everyone don't hesitate to capitalize on the Free Pass they offer via the Onslow Fitness website. Check it out, you will not be disappointed!"
