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 a bag with water and sportswear and wear sneakers. Gyms are generally not cold, just T-shirts for sportswear.

2. The gym is divided into equipment area and aerobic area. Generally, there will be a tour guide to teach you simply when you don't understand. But if you supervise your practice, you will have to pay for private training. 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.

4. Generally, the gym stipulates that you can't go shirtless, at least wear a vest. Yoga has an independent space, usually a yoga room.

The dressing room must be separate for men and women.

6. After going to the gym, most members are concentrating on exercise, and no one will have leisure to care about others.

7. The answer is the same as above

8. There is nothing mysterious about the gym. As long as you have a membership card, you can practice. The key is to know what you want to achieve, whether to lose weight or gain muscle, and then work hard. The gym has a good atmosphere and is full of civilized people. It won't be messy.
