(I have NOT read this advice yet on this forum, but elsewhere and wanted feedback.)
From what I know and what I've observed human babies try to walk before they can free stand.
They lean against furniture or stairs or people and immediately try to walk, NOT stand still. They learn to stand for extended periods on their feet unsupported long AFTER they have been trying to walk. One guy who recommends this writes a lot about taking a lot of intermediate steps in learning to handstand, and taking an easy path so one does not get frustrated and quit, but then contradicts himself and takes this stance which introduces a large gap in the progression.
What's this board's opinion, and are there any valid ways to arrive at the "train the extended stand before trying to walk" advice?
Another thing occurred to me: even if going for the free standing stand first was the best practice for teaching handstands to most people, wouldn't there be outliers (like there always are) who have slightly different muscle strengths from the majority (or better neural control of different actions, or just a deeply rooted personal preference for movement over stability, or ...), for whom walking would be very, very easy and a good way to learn how to be upside down? So for me the blanket, one size fits all nature of that advice also rankles.
