Every few years there seems to be some new fitness fad that claims to help you get in shape. It could be simple stretches designed to tone your body to choreographed dance routines that are geared to work up a sweat.
UK-based health and well-being site Beneden UK created a video highlighting popular fitness trends dating from the 1910s through the 2000s.
The video was posted last month and has picked up traction with over 2 million views on YouTube.
Sit back, relax and enjoy the journey through 100 years of fitness.
