The analysis or breakdown of kata in known as bunkai. My #1 rule for bunkai is that it should help us practice against realistic attacks like we see "in the street" (non-consensual violence). There is a lot of great material out there but there is a lot of less-than-great material as well. This video is the first in what I hope will be a series. In the video, I provide examples of bad bunkai that break this important rule. I do not mean to be offensive but I think it's important to identify ineffective practice even if it comes from people who may be highly regarded.
