How old do you have to be to work out there?

I’m 17, I go there all the time by myself. All I had to do was have my parents sign on for me when I first signed up. After that you’re okay to go in without parents

Think 18, but i know parents go to gim with child sometimes

I think 18. You can call them. There's also a YMCA here too

18 I believe not sure if accompanied by parent.
