Closed Guard to Armbar by Under Hooking Leg (Fundamentals)

Professor Lucas Lepri shows how to get the armbar from the closed guard, by uner hooking the leg. Lucas has the opponent in the closed guard and controls both sleeves. He picks a side and under hooks that leg while still controlling the other sleeve. Lucas now opens his guard so he can pendulum his legs and shifts his hips to the side. From here, he brings his outside leg over the opponent's head and gets the armbar submission.
