You have to wait two years, a lot may change and info you get today may be out of date.
Yea just bring an adult
Once u turn 13 u can go with ur parents or someone 18 or older. But for the age u r now go to the ymca or see if whatever high school ur near has an open gym n go with ya dad or an older cousin and be mindful that it's real weights an not toys. And enjoy your workouts. But also just start from home do pushups, go to walgreens or walmart and buy an iron gym and use that and some resistance bands n some dumbbells. And u don't have to worry about a gym membership for now n be able to use your gear when your ready. Hopefully I helped you out some.
I think you have to be with someone 18 or older to go to Planet Fitness. Perhaps the YMCA will allow you to go to their gym, but I am not sure. Good luck.
Yes you can come but you need a parent to sign a waiver for you
