I mean i see alot of smiliarities in the training of Goju and Uechi Ryu, Ive seen the Uechi Ryu masters use the iron body, basically striking there students in various area's all over making them strong enough to take a 2 by four to there body and not budging, they use the pots to make there fingers strong and they are able to break boards with them, They make there wrists strong and are able to break baseball bats. Ive seen the same pots used in Goju, but ive also seen the stone hammer, and other weights, that go on the feet, neck, and hands. I dont know if Goju has the same iron body as Uechi though i havent seen it. Kyokushin has iron body as well similar to Uechi So whats the diffrence between these arts? Which art is better for modern defense? Which makes the body stronger and which makes you faster?
