#3 No Retreat, No Surrender
One of the weirdest fitness training montages in this list, Jason Stillwell (Kurt McKinney) is trained by the ghost of Bruce Lee to become a top martial artist. Stillwell must eventually face the evil Russian Ivan Kraschinsky (Jean-Claude Van Damme, of course) to try to win back the respect of his family and friends. Stillwell's training includes sit-ups in a playground, using those old steel bands that can cut your head off if they slip out of your hand, outrunning his friend on a bike and beat-up hanging sand bags. If the song doesn't inspire you to never surrender, his cheesy red headband definitely will.
