Gym Simulator is an unusual simulator with a first-person view, in which you have to devote your life to a fitness club, daily pumping up your muscles and body as a whole, and also trying to get a girl from the gym into bed, who, by the way, will not communicate with a skinny guy and a boy who doesn't represent anything. The main character's body will become larger and more massive depending on the amount of training done, and NPCs will begin to treat him better over time.
