A new viral video pays tribute to fitness trends from the early 20th century to the present day, where Zumba! classes are apparently all the rage.
Produced by Benenden Health, a healthcare service in the U.K., the clip showcases every fitness fad, such as stretches dating back to the 1920s that mimic the Charleston dance moves, and the Trim Twist, which dates back to the 1960s and consists of a brown board that women would stand on to twist away "bulging thighs" and "heaping hips," as one advertisement put it.
The montage will also bring back memories of Jazzercise, 80s aerobics and workout wear that consists of wearing fanny packs over brightly-colored leotards — and aren't we glad those days are behind us?
