Be Born to a Mom With a Great Butt
(Hi Mom! Thanks for that!) Or at least have some good butt genes somewhere in your family. I am a carbon copy of my mom, and my pear shape fell directly from her tree, but you might be able to find a booty role model on a more distant branch of your own family tree. Your aunt? Your paternal grandmother (check the old black-and-white photos to see if back in the day she was working some back)? Good genes are without a doubt the most efficient way to get a great butt, so keep looking until you find some.
