Professor Lucas Lepri shows an attack from a defensive open guard position to the single leg takedown. Lucas’ opponent is standing and trying to pass. As soon as the opponent grips Lucas’ pants by the knee, Lucas immediately places his hands on the opponent’s biceps and grips the Gi with his palms facing in. The opponent tries to pass and Lucas uses the grips to keep the opponent away. The opponent steps to one side and then to the other. As he steps to the other side, Lucas blocks the arm of the same side the opponent steps and pulls the opposite arm in towards his chest, unbalancing the opponent. As Lucas pulls the arm, he reaches for the same side leg and goes for the single leg takedown.
