As the person who answered it in the first place, I'll admit that it took a lot of work to try to pull an on-topic answer from the question. At the time that it was answered, we had little direction for the site, we had no FAQ, and we had no moderators (other than community team, which is extremely busy).
As it stands now, the question is very broad in terms of our scope (our scope is a small fraction of the scope of that question), which qualifies it as "Not a Real Question".
Further, since by your own explanation the proposed practice is "standing practice" that would lead to an explanation, we could easily replace the phrase "martial arts" with "pilates" or "yoga" (as examples; we could include numerous other exercises, including gymnastics or dance) and the answer would hold as much merit. This makes the question no different than "How do I use Excel... for martial arts?" Thus, the question is off-topic as well.
Finally, in response to a question having an answer, this should be stated and in big bold letters:
Answers to questions are chosen by the asker; it is not up to the asker but the community to measure the validity of a question for this site.
