“Brazilian Jiu-Jitsu (BJJ) is a grappling-based martial art whose central theme is the skill of controlling a resisting opponent
in ways that force him to submit. Due to the fact that control is generally easier on the ground than in a standing position,
much of the technique of Brazilian Jiu-Jitsu (BJJ) is centered round the skill of taking an
opponent down to the ground and wrestling for dominant control positions from where the opponent can be rendered harmless.” –
