Men's bodybuilding is a competitive sport focused on developing and showcasing muscle size, symmetry, and definition. Participants, known as bodybuilders, engage in rigorous weight training and follow specific nutrition plans to enhance their physique. Competitions often involve posing routines where athletes display their muscular development to judges. Bodybuilders typically prepare for competitions by undergoing a process called "cutting," which reduces body fat while maintaining muscle mass. Events are categorized by weight classes, and athletes are judged on criteria such as muscle tone, proportion, and overall appearance. Prominent organizations like the IFBB (International Federation of Bodybuilding) host various competitions worldwide.
