Q: Is bodybuilding a sport? Why or why not?
No, bodybuilding is not a sport. It is a male beauty pageant, the aesthetics of the body being the "beauty" in the pageant.
In order for bodybuilding to qualify as a sport, winning in it, on the day of a show, must depend 100% on
the performance of a physical skill. In bodybuilding, on the day of a show, the "skill" portion of bodybuilding is posing. Winning in bodybuilding only depends around 10% on posing, 90% on how you look. You have a little bit of ground to make up with skill, but not much.
Again, in order for bodybuilding to be a sport, it must depend on the skill portion
100%,
not 10%. Therefore, it is not a sport, but rather a male beauty pageant.
