Onslow Fitness, the best 24/7 gym in Jacksonville, offers the most comprehensive amenities in town. More than just a gym, we are a full-fledged fitness center that offers every service you could need from working out to recovery.

STEAM ROOM and dry sauna


An overlooked part of many fitness programs is proper recovery. Our dry sauna and eucalyptus-infused steam room help members recover from workouts so they’re ready for the next one that much sooner. Health benefits from dry sauna or steam room use include:

  • Greater Flexibility & Less Muscle Stiffness
  • Increased recovery time and general relaxation
  • Improvement in circulation, removal of toxin and respiratory benefits

    Free Childcare


    We know how important it is for parents to recharge, manage stress, increase their energy, heighten their mood and manage their weight to keep up with all of life’s parental responsibilities and demands. So we try to make it as convenient and comfortable as possible for you to enjoy your Mommy/Daddy time in peace, and the onsite childcare services at our Jacksonville gym ensure that children are completely secure, safe and having fun while you’re working out at Onslow Fitness!


    Onslow Fitness knows that sometimes, especially when the weather is nice, and you’ve been cooped up in the house or in the office all day, an outdoor workout is the way to go! For this, our gym in Jacksonville has added our outdoor functional training area.




    Our clean and secure locker rooms will make you feel right at home when you are freshening up after your workout.

    Our men’s and women’s locker rooms feature the following:

    • Individual Lockers (please bring your own lock to secure your belongings)
    • Private showers with soap
    • Hair Dryers
    • Private dressing rooms
