There are millions to tens of thousands, depending on the local consumption, the club hardware and equipment, and the contents of your annual card (such as whether there are coaches or not, whether there are some courses). If not, if you want to take other courses, you need to pay extra.

About the effect after practice: there is still some, and the most important thing is whether you can persist.

Ordinary people's psychology: I feel that my body will be better soon after I get the card. It seems that I can see myself in a few months, and I feel good after a week, and I feel that I will succeed. After a month, I got bored and didn't want to go. I am too busy to go tomorrow.

About the benefits of doing card fitness: there are mentors, partners, competition and circles.

About the disadvantages of getting a card: ask yourself first, how many days have you been doing it, and 80% of people will not go after doing it.

Personal suggestion: download KEEP. That exercise is the same. The key is whether you can persist. If you insist, make one. If not, don't spend money.
