Reminds me of many exquisite ‘low stance’ torture sessions in the dojo.
Pushing to such high levels of flexible fitness is really worth it though; it obviates all kinds of negative crap, and the torture gives way to the pleasure of having acquired the easy expression of craft (my favourite word for translating ‘gong’, deeply ingrained skill, ability).
The low stance torture sessions are in past tense for me now actually.
But I value my martial arts training for having shown me what is possible in terms of pushing into high levels of fitness, which I now maintain at the gym using a combo of fitness machines, yoga and qigong. And the all important sauna to top off the workout…
It’s true that excessive low stance work can be dangerous, and in any case, painful.
