Here’s a breakdown of one of the rarest and most exotic submissions in Brazilian Jiu-Jitsu, The Z-Lock, which attacks primarily the hip joint.

The Z-Lock submission became popular last year when leglock master, Eddie Cummings, posted a video in his Instagram account.

Since then, this is potentially the first time that the submission has been successfully used in competition, when Edwin “Junny” Ocasio faced Justin Ordinario at Fight to Win 146.
