Brazilian jiu jitsu is a grappling-based martial art whose central theme is the skill of controlling a resisting opponent in ways that force him or her 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 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./ Z8 n6 q# s7 Q( `5 M( ^9 v http://www.urbanatomy.com/site/shbjj.htm 2 B% `. @. m' j+ a/ l
