Here’s a fun and unique way to work up a sweat. Try one of these five wacky vintage exercise videos, selected by Blisstree.

We got caught in a retro-fitness wormhole. Once we started we couldn’t stop! Luckily, the internet is ripe with weird stuff from the past. Lifestyle advice from vintage magazines and old videos provide such great insight into bygone eras, sometimes there are even good tips and techniques that have gone out of style. Some of these workouts are totally doable in your own home, others not so practical. They are all worth checking out for likeminded retro-enthusiasts.

Here are 5 fun vintage workouts you can do online:

How To Become Slim

One of the oldest workout videos I’ve ever seen, this 1931 routine intended to help women “reduce” enough to fit into the stylish longline dresses of the era. The moves are fun and you’ll feel like wearing a romper and little heels to workout.

Vintage Glamour Girl Workout 1940s

This video opens with bust exercises. A lot of the moves in this throw back remind me of Pilates. The narrator is an insulting old timey misogynist, but look at those outfits!

The 90s Workout

Another aerobics workout, this time serving up the 1990s. This video is so goofy–you get to do the running man. One commenter on Youtube called it a “white goth hip hop workout on a chessboard…hilarious” and they are 100% accurate.
