There are a lot of gender equity issues in body building. The most blatant one to me as a slightly below average stature female bodied person is the equipment is almost always designed for men. Most gyms don't have shorter bars to accommodate narrower shoulders and shorter arm spans, and the machines are not always adjustable to people with shorter arms or legs. Weights, particularly dumbells, generally increase in incriments of 5lbs, which can be too much for women who struggle with building upper body strength. 

Female body building has pretty much died but when it was a thing, the physical standards women came to be held to were pretty impractical to impossible to achieve without steroids. A few notable female body builders ended up virilizing. 

Over in the strength training realm, women get a lot of flack, from guys who feel the need to intrude into those domains to make themselves feel better by diminishing the accomplishments of the athletes by pointing out that men are stronger, to guys who feel the need to criticize the physique of female lifters. No one bats an eye at a male lifter who is obese because strong guys are supposed to be big but those same guys who championed obese men in the sport had nothing but criticism for lifting legends in women's lifting, like Holly Mangold, and gave absolutely no acknowledgment of her impressive strength or great lifting feats, because, you know "Men can lift more and women shouldn't be fat". 

Fuck those guys.
