I am not from Chengdu, so I don't know. But? Go to the gym for fitness, and the environment must be good. Good lighting, fitness equipment should not be too old (to avoid accidents). There must be central air conditioning. It is best to have 3~5 coaches every day, and then watch the courses offered by the gym every day. More elements are needed, and more than 5 hours of classes can be guaranteed every day. The coach looks chubby. If you exclude the muscular ones, you don't have to go. Those are novices who always like to treat us ordinary people as fools.
