Professor Lucas Lepri teaches how to defend from a side headlock and get the armbar submission. The opponent gets Lucas in a side headlock and Lucas starts to defend by reaching behind the opponent to control the waist or arm. He then cups the back of the near side leg with his hand, using the C grip. He drops his leg in between the opponent’s and takes him down. Once on the mat, the opponent still maintains the head control. Lucas goes into detail on how to escape. When he is able to make the opponent release, Lucas then immediately goes for the armbar submission.
