The Rocky theme, widely known as Gonna Fly Now, was composed by Bill Conti for the 1976 film Rocky, where it accompanies Rocky Balboa's famous training run through Philadelphia. Its bold brass melody became inseparable from the film's underdog story and was reused across the Rocky sequels, helping it stay instantly recognisable decades later. Online, creators adopted the louder, punchier version for workout clips, motivational edits and parody montages, where the music alone signals determination, effort and a triumphant finish.
