Bodybuilding is not a sport. In fact, bodybuilding is no different than a beauty pageant (minus the beauty of course).
Also, for those who think bodybuilding is so difficult, take a look at what your average NFL football player or triathlete puts their body through during a typical season. Bodybuilders eat, sleep, shit and train....give me a break! Your typical NFL player trains with weights during the week and then goes out on Sundays and competes in a truly brutal athletic event.
As mentioned, bodybuilders are judged based on the way the look, which negates a sporting classification.
Lastly, bodybuilding requires absolutely no skill...no superior hand eye coordination or quickness + speed. It's not a sport and pro bodybuilders are not pro athletes.
