If your footwork sucks, you fighting will suck. I'd say its definitely the most important thing to get right. If you dont have a solid foundation you cant throw a proper cut. Good thing is, once you've learnt it, it also translates to other martial arts.

How do you recommend fixing the problem of people getting too close due to their forward inertia during drills with two or more strikes? For example, Zwerchau to the opponent's left, then throwing another Zwerchau to the opponent's right in response to being offset? I find that students, myself included, tend to get so close with that second Zwerch that they're practically hitting with the strong. Do you think a drill where the opponent attempts to stop the second Zwerch with the slice or even a grapple would encourage control in that second Zwerch and the right distance management? Love your videos, by the way.

Excellent. Not far from a wrestling stance.

I appreciate your effort and the time you took to make the video. However, let me give you my personal input and try not to take it personally. Too much talking, not enough showing. I watched 5 minutes of the video and still have no grasp of the proper footwork. Why not just make a short video showing proper footwork and then common mistakes, with text commentaries below or in between footages? I believe it would take a lot less time and would be a lot more convenient, especially for revisiting, which is necessary for learning. You can even add timestamps for further convenience if the video becomes longer than 3 minutes.
