What is Brazilian Jiu Jitsu (BJJ)?
Brazilian Jiu Jitsu (BJJ) is a systematic based approach to grappling. The focus of BJJ is twofold: (i) to control your opponent through leverage, grip, and position; (ii) to isolate either your opponent's limb or neck and manipulate it such that the applied breaking force on their joint or the strangulation making them submit by "tapping out".
There are two variation of practicing BJJ, Gi and No-gi. In the Gi version, practitioners fight in kimono gear, making use of collars, sleeves, lapels, and pants to assert dominance of control and submit. In the No-gi version, there is no kimono. Hence the name "no-gi". Practitioners instead wear rashguards (often compression shirts) and shorts. With the obvious lack of Gi to make grips, No-gi practitioners must control and submit their opponents with the focus on using wedges, pins, and body grips.
