A breakdown regarding a basic jiujitsu submission.
“the kimura is a very versatile tool as a submission attack. (Its versatility was innovated as a “trap system” by David Avellan.)
The origins of the attack differs from catch-wrestlers to judo. In BJJ (Brazilian Jiujitsu) it was named after ‘Masahiko Kimura’ who broke the elbow of Helio Gracie (founder of BJJ.) with this attack.”
