Gizmodo points out this excellent YouTube video showcasing the surprisingly agility of knights in full plate armor.[ref]Email subscribers will have to click to view the article because videos don’t embed in the emails.[/ref]
Running, climbing ladders, getting up unassisted, jumping jacks, rolling on the floor: the armor is definitely restrictive versus wearing none at all, but the range of mobility is really surprising given what I’d expect. Also, as a bonus, there are some reconstructions of sword fighting techniques at the end of the video based on ancient manuscripts. Very cool video.
They’re sure not very sneaky.
There is quite a bit on youtube that follows into this kind of stuff. Much of it is very interesting to watch.
