Martin Höppner, the head instructor at Schildwache Potsdam (DE), a club which focuses on the sources of Renaissance Italy, shared this video a few days ago. It’s one of the best I’ve seen on how to teach a technique within “HEMA.” It is worth watching.
Students with a traditional/classical background will recognize the structure of this lesson well. There are a few things Martin mentions, if briefly, that one will likely spend a bit more time on in an actual lesson, but for a video just shy of 17 minutes one will be hard put to find a better distillation than this.
