See if you do everything. Does the bag include swimming? At least 200 square meters. If it is a gym, you must have a general aerobic exercise area, a strength area, a large exercise room, a spinning bike, a yoga classroom and, most importantly, a place to take a bath. 200 square meters is very small. If you go to the gym, the environment must be very comfortable. If it is too cramped, it will make people feel very depressed.
