Professor Lucas Lepri teaches a drill on neutralizing the butterfly guard and getting the back control. The opponent has the butterfly guard with his back on the mat. Lucas immediately grips both collars to start defending. The opponent now starts to lift Lucas in an attempt to attack. Lucas starts to walk to the side while using his opposite side elbow and knee to block the opponent. He circles the top hook out and moves back to the side so he can use his other knee to block the hip. The opponent starts to turn away and Lucas lets him. As the opponent is turning away, Lucas takes the back control.
