I originally learned this form/drill while training in Jerry Poteet’s linage while he was still alive. This drill is what I base my Jun Fan/JKD material off of when teaching my students. Ron Balicki said that we should learn the drill and then forget it, and that is the philosophy I share with my students. That is how we achieve “being formless”. I like the way this Sifu does the drill and use his video for reference.
