The Turtle DVD with Josh Russell - Never get tapped from the back again!
This DVD covers:
Defending from the Turtle
Reversing from the Turtle
Attacking from the Turtle
"The turtle is a common position in Jiu Jitsu. Sometimes you need to go to your knees to avoid your opponent's side mount. I will give up one advantage point to avoid three points. Sometimes if you are down on all fours you have to open up so your opponent has to move. That is when they make the mistakes that cost them the fight."
