The music is Gonna Fly Now, composed by Bill Conti for the 1976 film Rocky, where it accompanies Rocky Balboa's training montage and run up the Philadelphia Museum of Art steps. The track became a cultural shorthand for perseverance and has been reused for decades in sports broadcasts, gym playlists and parody montages. Online, short clips of the fanfare spread as a quick way to turn ordinary effort into a heroic moment, keeping the theme instantly recognisable even to viewers who have never seen the film.
