Hey, Black, if you ever wanna build on the I Ching hit me up.
Yeah...we condition by for example hitting our forearms against another persons and building up. No joke some of the guys I train with could pretty much take a baseball bat on the arms. Xin Yi was also meant to take on weapons so I guess that's why it is so empashised. We also do chest, back, stomach, legs....basically every where.
With my arms...they actually rarely bruise any more unless I go EXTREMELY hard. But in the period where they did bruise I also got tired. I assume that's just the body recovering.
I never realized all the years I did karate that my arms and hands actually coulnd't handle me hitting someone as hard as I could.
I am currently a bit sceptical on alot of "Chi" stuff....not all but I find there is a huge correlation between the amount of magic powers promised by a teacher and the amount of books or stuff they want to sell.
Wisdom is better than rubies and all the things that may be desired are not to be compared to it
