No Gi World Champ, ADCC Veteran, and Atos HQ black belt Michael Perez teaches the Basic Wrist Lock Submission, during the 730am Fundamentals class on 06/13/2018.
Although wrist locks are very effective if done properly, they are not common submission in the BJJ. Wrist lock can be done from deferent positions like standing up in a grip fight (just like the video), bottom closed guard, side control. Great opportunity to pull off this submission is from failed armbars or omoplatas.
Mike Perez received his black belt - 1st degree from Atos Head Coach Andre Galvao in October 2017. He is a Kasai II Grand Prix silver medalist; a IBJJF Pans No-Gi bronze medalist; and a 2x ADCC US Trials Champion.
