Brazilian Jiu-Jitsu is a martial art & combat sport that is in constant evolution and is now a requirement for anybody who wants to know self defense or practice MMA.
John Danaher, Bernardo Faria & Gordon Ryan explain how body mechanics can relate to Jiu Jitsu.
Danaher goes into detail on how a system requiring 2-6 step is the ideal. Both champions Faria and Ryan practice Jiu-Jitsu at the highest level but they represent two spheres of our sport. Gordon Ryan is known for his No Gi game, leg & back attacks and his floating passing system. Faria is a master of the Gi pressure passing system and deep half guard and Faria sweep.
To be an efficient BJJ practitioner, you need first and foremost a deep understanding of body mechanics.
