Generally, the gym is about 1500 a year (of course, it has something to do with the local economy) and about 1000 a year. Eat and drink according to your usual consumption level (I don't know, you can buy chicken and cook it at home, or you can eat steak every day, depending on your personal consumption ability and habits). If you plan to drink protein powder every month, you have to add 300 yuan every month.
