Except for winning competitions, is there any natural advantage of bodybuilding for both men and women? For both, for advantage in most sports and attractiveness the typical calisthenics physique, sort of gymnast/football(soccer) one seems like the ideal one to me, yet a lot of people seem to be obsessed with getting overly buff.
By bodybuilding, you probably mean steroid-fueled muscle building. Most natural body-building will never reach that level. On the other way, there is plenty of good health reasons to train with weights, and build a good/solid muscle mass. It also improves a lot of other aspects in your life (social). So, weight-training, bodybuilding - lite is great. Steroid ladden/extreme body building one is probably not healthy.
Know well that something as simple as visible abdominal muscles already requires a body fat percentage that is lower than what is generally considered healthy.[0]
One's musculature should not be “defined” for optimal health, — that requires dropping below healthy fat levels.
Professional body builders go far beyond that, of course.
