If you plan to keep fit for a long time, you can consider getting a card first, and don't listen to too much sales promotion. There will be a discount for short-term or group registration. The other thing is about the course. Don't worry, just say you get used to it. Go to the gym after getting the card. If you feel the need, you should take the initiative to ask about the course. Otherwise, you don't know anything, and it's not good to sign up for a course that doesn't suit you.
