It seems that way for just about everything when it comes to teaching for some. Like even cooking, if you're a beginner they still can unintentionally skip the basics because it has become second nature to them and they forget.

In case you're open to suggestions, I've seen Fitness Blender frequently recommended. It sounds like it might have some options. Sydney Cummings might be the one I heard about having apartment friendly videos. But I can't speak from experience on either of those since I do my own thing.
