The classic training montages. Probably you could throw in some Van Damme here, too.
For some reason I currently just remember some random ones although I should and do clearly know more:
“The Ecstasy of Gold” from THE GOOD, THE BAD AND THE UGLY:
The opening of UP which is just music only (Sorry, Thor, Giacchino, but one of his best scores ;-)):
The construction scene from EXPLORERS with Goldsmith’s music (IMHO best track of the score…):
(Which reminds me of the current construction scenes of THE A-TEAM somehow ;-))
