The only heated indoor saltwater pool in Jacksonville
Our pool stays at 87 degrees all year, so it's a comfortable place to train, recover or take it easy on your joints. Saltwater is gentler on your skin and eyes than a heavily chlorinated pool.
Every new member starts with one-on-one time with a certified trainer, so you know how to use the club and what to work on.
Kickstart session
A trainer reviews your goals and history and walks you through a short workout at your level.
Fit3D body scan
A 3D scan of body fat, lean mass and posture, sent to your email, so you can track progress.
Equipment orientation
Learn the machines, how to set them up and how to pick the right weight.

Questions
Before you come in
Is the pass really free?

What can I use with the pass?
Everything a member can: the heated saltwater pool, group classes, the sauna and steam room, the training floor, the outdoor training area and the Kid's Club.
Can I bring my kids?
Yes. The Kid's Club takes children from 6 weeks old for up to two hours a day, first come, first served. It's open weekday mornings and evenings and Saturday mornings. Full hours are at the bottom of this page.
When can I come in?
Pass visits are during staffed hours, so someone is there to show you around. Members get 24/7 access with their key fob.
I'm just getting started. Is this a good fit?

What happens after my pass?
If you'd like to join, we'll walk you through the membership options and get you set up with a free Kickstart session with a trainer. If not, no hard feelings.
