‘Ili’s link earlier this week to the 1988 National Aerobic Championships reminded me of this movie: Heavenly Bodies (1984). It’s a Canadian aerobics movie (yes a real genre) that ends with an aerobics-off.
Other notables in the genre: Ron Harris’s Aerobicise (1981) and Flying (1986), which stars a very young Keanu Reeves.
