Membership cards can be discounted indefinitely, and you can also enjoy activities with gifts or more discounts. Usually it's the same as others, but the annual card is used within one year. It doesn't make any difference whether you use it or go there several times or dozens of times, but by the end of one year, your money will be zero. If you want to go again, you have to pay another fee and continue for another year. However, each gym has different regulations, and the final interpretation right belongs to the gym.
