In an era when a t-shirt and jeans is increasingly considered appropriate professional attire, it can be hard to imagine wearing an itchy, constrictive suit to work every day—let alone a suit of armor. But back in the 15th century, knights did just that. And it turns out, despite the fact that their uniforms were made out of metal, knights were able to run, jump, and fight with impressive agility.

In the short video above, Paris' Musée national du Moyen Âge collaborated with The University of Geneva to show what it was like to wear 15th century armor. In the video, two "knights" demonstrate traditional fighting techniques and show off the impressive range of movement armor allowed by walking, climbing a ladder, and even doing jumping jacks.
