1. Firearms are against the 24 Hour Fitness member contract. It's in the fine print, but it's not enforceable 30.06 language. If discovered, you won't be guilty of criminal trespass, but they can cancel your membership without compensation. I prepaid for mind, so that's a lot to lose. Concealed is concealed.
2. I keep a j-frame in my bag and normally I workout when it's slow enough that I can keep my bag with me.
3. The SuperSport where I go has a few private locker rooms with lockers, a toilet, and a shower inside. If you really need accommodation (and your gym has them), consider using those.
4. I agree with others regarding intentionally failing to conceal. A public restroom / locker room is still public. You have an expectation of privacy in the toilet stalls, but not in the locker room. (You have an expectation of privacy in the locker room to not be video recorded, but that's about it.)
5. I also looked at their video screens to know the security camera coverage for the parking lot. You might be surprised at which spots are covered and which ones aren't - the camera locations can be misleading. I always park squarely in the picture and you can see every approach angle of my vehicle. This tip was to help you, but if you go the same club I do, don't take my spot!
