Does the gym pay for half a year? Or a membership card for a few months or something. Because I want to keep fit. I never understood it, so I was afraid to go. Who can help me?

Yes, there are four kinds of fitness cards, monthly card, season card and semi-annual card. The longer the time, the more cost-effective. Don't be afraid, everyone starts from ignorance. The coach will tell you a lot of basic knowledge of fitness when you go. Don't worry, you have communicated more than the coach. Ask if you don't understand.
