I was not online, my conditioning is not extreme actually pretty standard for okinawan karate and very similar in concept to muay thai, iron palm etc...The key concepts are gradual to allow adaptation and liniments immediately before and after. So I target hands (every possible part, included fingers),wrists, forearms every portion, shoulders, legs, shins, elbows, foot.
By the way the one blow one kill logic is not philosophy at all if you break with your hand bricks like they did in the old time,neither the say that the block should be also an attack if you have your forearm conditioned believe me people feel pain when they hit you
will this give me deformation?? Until now not, however this is the real karate way and Mas Oyama knew it; only in this way karate becomes a deadly self defence system and can compete with Muay thai, boxing etc....
