In this video we cover a pad drill for the first half of Seipai kata. This impact drill mirrors a two-person bunkai flow drill; that the video also shows. These drills should not be isolated from the wider training matrix of which they are part. That training matrix also includes drilling individual techniques, alternate combinations, variations in line with underlying principles, and the free-flowing applications in both semi-live and live drills. It is obviously not possible to show the entirety of such a training matrix in one short video.
