Under Armour TV Commercial, 'Rule Yourself' Feat. Stephen Curry, Misty Copeland

Stephen Curry of the Golden State Warriors, American ballet dancer Misty Copeland and PGA Tour golfer Jordan Spieth star in this powerful Under Armour commercial. Each athlete stands tall in front of a hazy neutral backdrop, looks forward with determination and begins to train. Then, we watch the bodies literally multiply to become armies of people synchronizing with every spin, swing and dribble. By the time these armies each go back to being a single person, we are reminded that we are a sum of our training.
