Yes, those are warm-ups.
Yes, I know people whose warm-ups look much like this. (Mine look sort of like this too, but only if you take it apart into components and do it at half speed and three-quarters as far. ;)
I've been rededicating myself to my martial studies this past month — with good results; I'm sore in places I can't describe again! — both for obvious reasons and as part of the NYE project, which connection I hope I'll explain in another video soon.
Anyway, the moral of the video is that if you love something and do it well, even the warm-ups will be badass!
(You think I'm joking, but I'm not…)
