1. Wear whatever you usually wear. The gym has a locker room, and everyone will have a locker. Remember to bring a lock. Just carry your own bag, put on water and sportswear, and put on sneakers. Gyms are generally not cold, just T-shirts for sportswear. 2. The gym is divided into equipment area and aerobic area. There are usually travel coaches, so it's easy if you don't understand. Then you'll have to spend money to teach privately. The equipment area exercises muscles, and the aerobic area is a treadmill or something. Generally, there are fewer people in the gym in the morning. Generally speaking, you can't go shirtless, at least wear a vest. Yoga has an independent space, usually a yoga room. The dressing room must be separated from men and women. 6. After the general members of the gym went, they concentrated on exercising. No one has the luxury to care about others. 7. The answer is the same as above. 8. There is nothing mysterious about the gym. You can practice with a membership card. The key is to know what you want to achieve, whether to lose weight or gain muscle, and then practice hard. The overall atmosphere of the gym is very good and the people are very civilized. It won't be messy.
