OK, so I'm a day late getting back to this.
Hso, to answer your question about training, I do not yet have a "sparing partner". I'm not really ready for one yet - because I'm still working on basic techniques with shadow boxing and mirror work - and it may take me some time to identify someone here with whom to work out. (I'm new in town, and most of my friends are not so inclined to carry sticks or use them for fighting; they either use other weapons or none at all.)
More to the point, because I'm so new at this, I'm still in the mode of carefully studying - watching and re-watching Glen Doyle's videos one technique at a time, then practicing, perhaps using a pole or tree to gently strike. (I also want to acquire a practice stick like he uses in this training videos. I know where he gets them, but the maker is in Canada and for some reason will not ship to the US.)
I often roll video forward, then click back several times to watch and listen. (His verbal descriptions are quite good; particularly that he offers key points to do and not to do.)
I only wish there was some free app that I could use to run videos in slow motion. He does most of his techniques once or twice in slow mo, but I'd like to slow that down even further.

Example: what I've been working on for several weeks - mostly as I walk, but sometimes in front of a mirror - are "stick punches" (his term) with left and right hand, as he capably illustrates and explains in detail starting at 0:28 sec in
this film. (Yes, lesson 1; I am truly a beginner.)
It took me two weeks of practice to get the hang of it. In addition to his key tips of keeping elbow bent and letting the bottom end of the stick bounce off the forearm (not elbow) so that it "re-chambers" immediately, I'm finding that my technique is best described as a left or right jab (from a position with both hands on the stick at about thirds) in which the stick acts like a whip.
I'm practicing high (head), mid-height (solar plexus, elbow) and low punches (as in for knees or groin, or bad dog) I fear the latter - dogs - more than a human attacker, having been attacked by dogs multiple times in my life. That is a major reason that I carry sticks.).
I'm still at the point of working out the kinks on the basic punch technique. My footwork for the punches still needs a lot of work. With the footwork, I feel like the kid that he's tutoring at 2 min into the video.
