Professor Lucas Lepri teaches how to get the triangle submission from the closed guard. Lucas starts to break the posture by gripping the collar and under hooks the other side so he can reach for the back. He grips the belt and turns to the side. The other arm is used to block the opponent’s same side bicep. Lucas then is able to push the arm in as he locks his feet together over the shoulders. He then adjusts his legs to lock and finish with the triangle.
