doesn't have alot of striking involved,it's an evolved grappling style...

here,did it for ya's;

Brazilian Jiu-Jitsu (BJJ) is a martial art and combat sport that focuses on grappling and especially ground fighting with the goal of gaining a dominant position and using joint-locks and chokeholds to force an opponent to submit. The art was based on early 20th century Kodokan Judo,[2][1] which was itself then a recently-developed system (founded in 1882), based on multiple schools (or Ryu) of Japanese Jujutsu.

It promotes the principle that a smaller, weaker person using leverage and proper technique can successfully defend themselves against a bigger, stronger assailant. BJJ can be trained for self defense, sport grappling tournaments (gi and no-gi) and mixed martial arts (MMA) competition.[3] Sparring (commonly referred to as 'rolling') and live drilling play a major role in training, and a premium is placed on performance, especially in competition.

like I said before Val,get comfy on the bottom.
your attacker can go from on top to waking up in a jail cell(or where ever you like) courtesy of a triangle choke...
