NAS Jax Fitness Center

Jacksonville's 275 gym listings cluster heavy around a few ZIPs. 32256 leads with 17, 32246 has 14, and 32207 rounds out 12, so if you're near those areas you've got plenty to sift through without leaving the neighborhood. Spread out further and the numbers thin fast, down to single digits in spots like 32223 and 32224.

Most listings carry a phone number (253 of them) and a website (231), so calling ahead or checking hours online works most of the time. Paid placements on this page carry a Sponsored tag, and none run in this category today, so what you're scrolling is unfiltered directory order, no bought spots mixed in. If you run one of these gyms and the site link or number stopped working, you can claim the listing and fix it, saving the next person in 32218 a dead-end call. Call two or three that match your ZIP and compare what they offer before picking one.
