Professor Lucas Lepri teaches how to counter the one over one under and get an arm triangle. The opponent starts to pass and under hooks Lucas’ top leg and also controls the bottom leg by reaching over it. In this scenario, Lucas is not able to reach over the opponent’s elbow to control it. Lucas instead uses the same side arm to cross face the opponent. He pushes the opponent down and to the side. He reaches over the head and cups the chin. The other hand goes under the opponent and Lucas connects his arm together by gripping the wrist. The opponent tries to defend and as soon as he lifts his hips, Lucas uses his foot to sweep the opponent over. From here, Lucas locks his arms together and gets the arm triangle.
