Last night a few of us were at the Quillian Center for class with Calderon Sensei. It was a really good class that put a lot of focus on seiza and shikko. A very interesting version of Shihonage was taught where instead of bringing your knee up immediately, you first raise your torso and hands for kokyo, then pivot and raise your knee. At this point, you roll backwards on your other foot and then push off backwards to finish doing Ura. Sensei said this is the correct way to do Shihonage Ura and when executed this way, it is veeery powerful. I don't have a video for this right now but once available I'll post it. Might be time to focus on seiza and shikko!
