Our school discontinued one-steps after about a year of it for me. I found it to be helpful but now insuffficient. Rather than teaching it against a punch as most of the initially are, it would be better to combine all attacks. We used to differentiate sparring combinations from these as they do not have self-defense type responses as do one-three steps. Sometimes the new student would think, hey I can do a knee strike while sparring. It was confusing, but then we dropped that part of the program. I think one-step, two, three sparring combinations would be helpful as a base for a new students to gain confidence, but for every attack. I tried teaching a couple of kickboxing students that way, and within eight weeks they were getting the basics down on how to move. Better than the throw you right in to the pot approach that our school does. TW
