Professor Lucas Lepri shows how to get the armbar submission when the opponent is trying to pass with one arm under. Lucas uses both of his hands to hold the opponent back. As the opponent applies forward pressure, Lucas shrimps out and brings his knees up to pinch the opponent’s arm. He moves his head back to stretch out the arm. His leg is now brought over and locks it with his other leg. Lucas can now finish the armbar from this position.
