Youtuber Thomas Jung struck gold when he found this riveting 1989 aerobics workout video and decided to make it better by setting it to “Shake it Off” by America’s sweetheart Taylor Swift (born in 1989, the very same year that all these people were dancercising).

Swift’s song matches perfectly with this workout video, in which approximately 1,000 enthusiastic, spandex-clad men and women clap a lot because they’re really proud of Taylor for selling so many albums, probably.
