Will it be bad to go to the gym and experience it for a long time before getting a card?
No, they will also want you to experience it for a long time. You can only get a card if you have experienced it. And now many gyms have good service. Some will be guided by coaches, and you can ask questions at any time. Of course, it would be better if you could go to private education, so they all hope that you can spend more after going through it, so don't have this mentality. Just experience it when you go.
