This is how people should teach and learn IMO. From day one, I've focused more on the positions as a whole, rather than individual moves. This is for everything, not just triangles. I think instructors over simplify when they just explain one move here and there. I get so annoyed when instructors teach a submission from guard, then a sweep from under mount, then an escape from side mount etc... The lessons should be tied together as tightly as possible down to if a person moves an inch, what are the new opportunities or threats that come from it. If you can't teach one move correctly, how are you going to teach several of them. I like where you're going with this and hope you continue to pursue this way of teaching but for a little constructive criticism, you were stumbling over your words quite a bit and seemed a little unsure at times. You need to speak clearer and without too much hesitation so you don't lose anyone in the process of explaining. Then again, a lot of BJJ instructors can barely speak english, so you're one up on them already. The moves could've been a lot more thorough in the explanation of the setup but it's not like you're a black belt, so it's fine. Other than that, great post. Thanks.
