Bodybuilding is an array of exercises and activities made to improve the muscular development and physique of the human body. Competitively, bodybuilders display prominent muscle mass, symmetry, and definition for aesthetic purposes.

The objective of bodybuilding is to control muscular development and promote general health and fitness. Being a top competitor would mean that the athlete has the correct muscle definition, mass, and symmetry as determined by their weight.

The only roles in this sport are the bodybuilders and their coaches, if they have any.

There is lots of equipment used for bodybuilding. Some basic necessities would be dumbbells, barbells, and kettlebells. Weight machinery is also very helpful in this sport, but not necessarily required. The basic weights offer the greatest range of variability in exercises, but the machinery offer the ability to change the weight you are using without buying additional equipment.

Arnold Schwarzenegger began weight training in 1960 when his football team began going to a local gym, but soon chose bodybuilding as a career over football. He won his first Mr. Universe title in 1967 as an amateur. In 1968, he moved to California to compete in bigger events. He won three more Mr. Universe titles, then went on to win the professional Mr. Olympia title six years in a row from 1970 to 1975. He then retired, but returned to competition to win the Mr. Olympia title once more in 1980.
