In case we needed another reminder that female athletes are total badasses, Under Armour's new "Rule Yourself" campaign showcases the incredible U.S. women's gymnastics team. Some people roll their eyes at a sport that involves glitter and pretty leotards, but this ad proves exactly how tough these Olympics-bound women are. Yes, they get their nails done, but they also get their ankles wrapped, climb ropes like ninjas, and work out tirelessly after dark. Set to M.I.A's heart-pounding "Matangi," the hypnotic acrobatic feats are truly next-level. We can't stop watching.
