A bodybuilder is a person who deliberately engages in activities designed to strengthen and enlarge the muscles of the body through exercise. This term can also refer to a person or company that builds and assembles the bodies of vehicles.
According to Self Growth, bodybuilders attempt to maximize their muscle hypertrophy through a sufficient combination of weight training, caloric intake and rest. Professional bodybuilders compete in shows where they display their physique to a panel of judges, who then assign points based on the bodybuilders' appearance. Muscle growth is triggered by the tearing of muscle tissue through rigorous exercise. Muscles grow larger and stronger during rest as the muscle tears are repaired.
