Something I’ve admittedly struggled with is reconciling the dissonance of ‘Jiu-Jitsu’ consisting of ‘natural body movements’ most everyone can accomplish versus positions that require degrees of attributes.
My conclusion is seeking to understand (and teaching if you teach) why the rules of a given domain are there in the first place.
Continuing on, with some domain savvy in place you can begin breaking rules effectively because you’re coming from a deeper place of knowledge than for example naturally flexible person who’s looking to plug their pliability into positions with no rhyme or reason, or more commonly, copying attribute driven games wholesale because you admire certain practitioner(s).
Going back to natural body movement, everyone reacts differently, and something as fundamental as a shrimp movement may confuse the hell out of some one and take awhile to get a hold of. Gold mined from things demanding perseverance aside, ALL Jiu-Jitsu requires at least some re-wiring and/or re-fining of muscle memory. This is, after all, what ‘training’ is. From this point of view, there is no such thing as a ‘natural body movement.’
To conclude, a very new place for me is a continuing study of the how and whys of the fundamentals of Jiu-Jitsu, along with leveraging my personal attributes (the beginning of art via ‘self’-expression), and continually improving other weaker points to ensure balance.
By contrast, used to scam myself into believing ‘Jiu-Jitsu’ would somehow give me all the cardio, strength, and flexibility I needed by osmosis through rolling??!! This resulted in a potential disaster luckily headed off by massage therapist who kindly pointed out that my hamstrings were perhaps the tightest of any client she’d worked on…;o)
