Pay attention to civilization, don't spit everywhere, don't talk loudly, you can ask a good coach if you don't understand, but don't disturb him when he is exercising. Put the trained equipment back and don't throw it about.

Pay attention to hygiene, wear vest, and some gyms can be shirtless, so the bench press or butterfly machine is full of other people's sweat. Wearing a vest is civilized and hygienic; Take a towel, you can wipe it in time if you sweat.

Be safe. I want to try everything when I go to the gym for the first time. Know a little about some equipment and ask others how to use it correctly. Dumbbells, barbells and other equipment, don't compare with others, don't be greedy, use the weight that suits you.
