Your lattisimus play a major role in connecting your upper body to your core. I believe arm techniques in general gain stability and power from engaging the lats properly.Smilar confusion exists here I just noticed if you see reader comments
Sanchin. The Three Battles of Kyokushin Karate
Sanchin no Kata made it’s way into Kyokushin Karate through the founder, Sosai Masutatsu (Mas) Oyama. Sosai Oyama had a background in various arts, including 4th Dan in Shotokan, 4th Dan in Judo, Taikiken, Aikijujutsu, as well as a 7th Dan Black Belt in Goju-ryu, under Gogen Yamaguchi.

Indeed on the picture of Sosai himself (and I habe seem that before)
it looks like that shotokan sanchin, not the current kyokushin version.
I know they change things, perhaps they change things from the picture to present?
But there has to be a reason for this. Someone must know why.
Even in the "The shodan" kyokushin book, by shihan Howard Collins the prescription there is both feet angled. But it does not seem consistent with how Oyama himself did it.
(I have also another related question here about the stability of uchi uke, when i play with this myself, my feeling is that the distance from body where to "lock" your arms, should be related to where your lower arm muscles meet your lattisimus dorsi? - that is a natural stopper, or so it seems ot me?
At least it maximum stability is a design princiuple? And then people have different muscles sizes, so guides about elbow one fist from the body, referring to which part of hte body, the side or the front? It's quite ambigous. I have received corrective feedback in class, where I feel that the arm and lattisimus dorsi loose contact and this I loose ALOT of stability. To the point where the only sensible solution would be an morote uchi uke, to compensate. Then I can't helpt wondering, what I am missing. Or is it perhaps the individual adjustements that the instructor is missing?? What do you think? It is ALOT esier to learn something if you get solid explanations.
All these similar small things in about everything is going on in my head, and I am honestly a bit annoyed to only get superficial teachings similar to "watch me, mimic me". I think there must be someone, somewhere that can explain constructing principles for moer techniques. Is there perhaps a good book for this, that focus on such principles rather than historical developments? The books I have mainly DESCRIBE, in words and pictures, but you can you read from a PICTURE of VIDEO, these constructing principles. Especially when practitioners wear baggy gi's that conceals precise body relations and contact points.
But this can be for another thread... )
