Professor Lucas Lepri shows how to defend from a single leg attempt. The opponent goes for the single leg and Lucas immediately slides his arm under the opponent’s arm pit, on the same side of the leg that the opponent attacked. Lucas uses his other hand to push the back of the head down. As soon as Lucas’ foot touches the mat, Lucas sprawls breaking the opponent’s grips. The opponent goes to the turtle position and Lucas goes to the side and controls the opponent.
