To highlight the change in fitness trends over the last century, Benenden Health has put together this 100-second video covering everything from hula-hooping to Zumba. As you'd expect, the world's favourite fads have come a long way since the early 1900s.
And the types of exercises aren't the only thing that's changed. Benenden reports women in the 20s dressed up in silk nightgowns and full make up for their Charleston-inspired stretches. Glamorous yes, but practical? Probably not.
Watch the video above to remember a time with Jazzercise was popular, then browse a few of our favourite sportswear buys below (leotards not included).
