Let's face it - the booty is extremely popular.
It's not only a marker of a man or woman who loves to attack leg day head on, but it's fair to suggest it's become somewhat of a cultural fashion statement for this generation.
With beats booming out of the US from the large luscious lips of Jennifer Lopez, Nicki Minaj and Beyonce, talking up the appeal of a large derrière, many men and women are now on board; every second instagram post from gymgoers today pertains to their "#bootygains."
For as long as it's encouraging trips to the gym and an active lifestyle - no one is complaining!
And for these women in Brazil, they've all well and truly got booty fever - vying for the crown of Miss Bum Bum in the events 7th year.
These pictured finalists have taken part in a 100m sprint in the streets of Sao Paulo, where they've been reduced to just 15 and with a winner being annouced in November in a live Final.
Some contestants couldn't help but to break out into a few body weight squats during the event - and it wouldn't have been their first time!


Booty Science
Further to the fashionable booty, women in brazil are more or less born with larger buttocks independent of trips to the gym, due to what's been identified as a mutated gene called "callipyge" (1).
Callipyge translates to "beautiful buttocks" in Greek, and allows one to have a larger bottom with little fat.

And would you believe that in sheep - it enables them to convert food into muscle 30% more efficiently than the other sheep (1).
Miss Bum Bum Contestants
Now with all this being said - the Brazilian Miss Bum Bum contestants are all showing plenty of Callipyge in the quest to be awarded the winner.
