From body + builder.

1. (bodybuilding">bodybuilding) A person who uses diet and exercise to build an aesthetically muscular physique, in order to compete in bodybuilding">bodybuilding.
   Physique of powerful bodybuilder (below) is like piece of sculpture. Buffs strive for the well-rounded body, disdain the professional weightlifter, who merely develops a number of very specialized muscles. December 1964, “Muscles are his business”, in Ebony, volume 20, number 2, page 148
   Because it is necessary for a muscle to rest while it grows and because of the importance of balanced development, most competitive bodybuilders train on a split routine; they work certain parts of the body one day and rest those muscles the next while they work the others, alternating like that six days a week. 1974, Charles Gaines, George Butler, “chapter 2”, in Pumping Iron: The Art and Sport of Bodybuilding
   In the competitions, bodybuilders go through "mandatories"—a set of mandatory poses—in the morning, where the judges compare the body parts of the builders. 1991, Samuel Wilson Fussell, “chapter 4”, in Muscle: Confessions of an Unlikely Bodybuilder
