Just saw post about Donnie Abel newsletter and top 5 punching mistakes. Perhaps this has already been discussed here but I didn't found any. Anyway that video makes me think about Okinawan fist, I suppose you all know what that is and my question is quite simple. They say it makes fist stronger but does it really? Does someone have better knowledge about human anatomy and physic? What this kind of fist is supposed to do?
I have practiced karate 6-7 years and last 2 years Okinawan fist, so I know I still have lot to learn how to punch properly, but this Okinawan fist doesn't seem to make any difference. It was nice experiment but for me it doesn't matter how my index finger is folded.
