Professor Lucas Lepri teaches how to get the triangle choke after defending some punches in the closed guard. Lucas has the opponent in his closed guard and the opponent starts to throw punches. Lucas defends by blocking the inside of the arms and then traps and controls the head and arm. The opponent tries to keep attacking and Lucas takes advantage of this and slides the opponent’s arm under his leg so he can lock the triangle. From here, Lucas can now finish with the triangle submission.
