Something else that helped me when I was trying to get this motion/trick down, at least for the hand movements, was to do a figure eight rotation with a staff, as the the hand movement is remarkably similar ....
lol, I recognize this under a different name*, but never realized it could be done in such tight fashion, I'd been doing this really wide and much slower. Cool lesson. I'm trying this with foam chucks and getting it right but notice I'm smacking the heck out of my elbows when doing it wrong, good think I'm not trying it with wood-chucks yet, lol.... * Sinawali weave, if I remember correctly, in Escrima is another name for this trick/move.
ken hill I learn this move early on in which I ripped a muscle in my shoulder because I didn't have the proper training like your video, wish this came out long time ago lol I think a good complementary video to this would be to how to execute this within moves, I have enjoyed your videos for years keep them coming please, good job bro
