Personal training.
Worth the drive from Fort Myers.

Honest answer: it depends on what you want from a gym. If you want a membership card and a rack of machines, Fort Myers has plenty of those and you should use one. If you want a coach who programs your training week by week, checks your form on every working set, and runs a room where the four people training beside you are there for the same reason, that is a rarer thing in Lee County than it should be, and it is what we do.

The drive works best for three kinds of people. Fort Myers residents who work in Bonita Springs or North Naples and train on the way home, so the studio is a detour of a few minutes rather than a separate trip. People who have already tried the big-box route and want a private studio badly enough to give it forty minutes. And seasonal residents in south Fort Myers and San Carlos Park who want a coach for the winter and would rather drive south than deal with a crowded chain in season.

Training is strength-first for adults who want to feel capable for the next thirty years: squats, hinges, presses, pulls and carries, wrapped in conditioning and mobility work, in 60-minute sessions. Small groups are capped at four so the coach actually coaches. If the drive means you can only make it two or three times a week, that is a perfectly good plan and the programming is written around it.
