McKayla Maroney, as you may recall, was on the women's gymnastics squad that took home the gold medal at the 2012 London games. McKayla herself grabbed the silver in the vault (she was not impressed, as you may remember). After a brief career as a famous internet meme, she really started upping her Instagram game -- to the tune of more than a million followers, if that's your sort of thing.

As for us, we love this girl's tenacity in the gym and her goofy personality outside it. Oh, and a booty toned over years of world-class workouts...that ain't bad either. Show some love this Olympics for this hard-to-impress hottie.
