Are you able to work out at 24 hour fitness without a parent if you are under 18?

I am under 18 and I have a trial thing for 24 hour fitness, and I signed up with a parent, but to actually go there and work out, do I need to have a parent with me?Are you able to work out at 24 hour fitness without a parent if you are under 18?Most gyms have a over 18 or over 16 policy. The best thing to do would be to contact the specific gym and ask them their policy.
