It is really impossible to give a unified answer, because people's age, gender, working status, living environment, health status, economic conditions, hobbies and so on are different. But in general, aerobic exercise can be considered as long as it is possible. No matter what kind of exercise, as long as it is aerobic exercise, it can be used as a way to lose weight and keep fit. As for what kind of exercise is better, it depends on a person's specific situation. For example, white-collar workers in their thirties and forties, with high income and busy work, can take part in running, swimming, skating, skiing, aerobics, badminton, table tennis, golf and other sports in combination with their hobbies, and can also practice equipment in the gym. Older people over 60 should exercise slowly and regularly, without drastic changes, such as walking, brisk walking, jogging, Tai Ji Chuan, ballroom dancing and yangko for the elderly.
Generally speaking, a person should exercise 1 ~ 2 hours on average every day. People who have jobs should exercise at least 1 hour every day on average. If you are busy during the day and have no time, you can do it at night. If you don't have time on weekdays, you can spend 2 to 3 hours exercising every day on weekends, which can basically reach an average of 1 hour per day. Older people who retire at home have more free time and should do outdoor sports for more than 2 hours every day.
