Professor Lucas Lepri teaches how to get a reverse armbar from the closed guard. Lucas starts with the opponent in his closed guard with the arm extended over the shoulder. He uses his inside hand to frame on the neck as he controls the elbow with his outside hand. Lucas now opens the guard and shifts his hips so he can bring his knee inside. He then brings his other knee up and places it along the opponent's shoulder. Lucas now moves his grips down to control the elbow. He now squeezes everything together and slightly turns towards the inside to finish the submission.
