Professor Lucas Lepri shows how to get the Estima Lock submission when the opponent tries to use his leg to prevent Lucas from passing. Lucas goes for a knee cut pass and the opponent tries to defend by using his leg to block him. As soon as the opponent brings his leg over, Lucas immediately locks the leg with the Estima Lock. He then bends in his outside leg in, so he can sit back as he uses his other leg to block the opponent’s hips. The opponent tries to bring his hips up and Lucas immediately places his other foot behind the opponent’s leg. Lucas then turns to the side and finishes the Estima Lock submission.
