Professor Lucas Lepri shows how to get to the back after passing using the double under. The opponent has the De La Riva and Lucas defends by pushing down on both legs. Depending on the opponent’s reaction, Lucas reaches under and over one leg to grip the opposite collar. Lucas’ other hand is still controlling the leg. As he pushes the opponent forward, Lucas then switches the leg grip to the back of the pants. The opponent starts to roll and Lucas keeps his hips next to the opponent. The opponent tries to roll once again and then Lucas takes the opponent’s back.
