Between high-intensity this and low-impact that — and of course the omnipresence of yoga pants — it seems safe to say that our society is obsessed with fitness. But that's nothing new!

There's even a viral video, with more than 1.5 million views on YouTube since it was uploaded on March 19, that illustrates that point perfectly.

The video, which comes courtesy of British healthcare service Benenden, is like a greatest hits for workouts, complete with an evolution of fitness fashion. And while we way not work up a sweat in long skirts and boots anymore, it's fun to see what was done and what was worn back in the day — especially when those days include '70s Jazzercise and '80s aerobics.
