This MARTIAL ART was born in the American PRISON SYSTEM - it is DEADLY!

Update: I was contacted by Sayf Carman who is the first man in the video shown. He has excellent martial arts skill and a wealth of knowledge and experience both on Jailhouse Rock and 52 Blocks. He sent me information about the “birth“ of 52 blocks and what I got wrong and i’d like to share it with everyone. Please follow his page here @@TheUmmahFightCamp “52 has a history that connects it to prison only because some people who did it “went“ to prison. It was not born in prison per se. It also would not do well under an average attack in the prison system since the 2 main attacks that take place are slashes and stabbings, both of which are best defended by moving into the arc of the slash and outside of the thrust. “ Please like and subscribe and if you really like the channel give it a share!!!
