Do you teach everything?

[Spartacus Maximus]

In the history of teaching martial arts it isn’t unheard of for an instructor to change their material. Sometimes by adding something or removing another. Even in the most traditional lineages there are those who, for whatever reason, do not teach everything their own teacher taught them. It could be a certain technique or an entire kata/form. 

For anyone teaching, is there anything you learned from your instructor(s) that you do not or will not teach? What would motivate you to make such a decision?

This is interesting.  I can't think of anything that I wouldn't teach;  maybe use some different approaches, but can't think of not teaching it.  But I definitely don't think I get to teach everything that I want.

On the other hand, there are some things in our curriculum that I would rather not teach, like our black belt three-step sparring.  I honestly don't think it offers anything constructive to the curriculum and is just curriculum for curriculum's sake.

There are quite a few schools out that there that have over a dozen fukyugatas and another dozen taikyoku katas on top of that (I'm exaggerating here, but you get the point) before you finally get the Pinan or Heian series.  Thankfully, my school isn't one of them, but if that wasn't the case, I'd consider it "fluff" that needed to go.
