To be honest, I've met many people who get a new year's card and then stop exercising. For them, the annual card is a waste!
The basic process of going to the gym is to get a card, then go in and register the key (everyone will have a special locker), then use various equipment to exercise (I won't say much about this), and take a bath in the shower after exercise. By the way, the general gym will provide free hot water, remember to bring a cup.
Some gyms will have some special courses and need to make an appointment in advance. This is also one of their marketing strategies, such as warm-up on Monday and yoga on Tuesday. You can refer to the course and call in advance to make an appointment.
However, we must first look at our own needs. Don't be passionate for a while. It will be a waste of money if you leave it at home after you finish it.
As for private education, it is usually arranged by communicating with the counter of the gym, which requires extra money, and generally teaches you how to exercise correctly. But to be honest, it's really unnecessary, so I don't know the price of private education.
I really don't know where there is a good gym except Shanghai, but you can go on a field trip. Generally, a bigger one won't be too bad. Gyms are almost the same, mainly depending on individual persistence.
There are other questions to ask.
