Professor Lucas Lepri demonstrates how to do the Koichi Gari takedown. Lucas start with one grip on the the opponent's collar. He uses his other hand to prevent the opponent from establishing a collar grip. The opponent then grips the arm that Lucas is using to grip the collar. As soon as the opponent grips the arm, Lucas takes a couple of steps back. When the opponent steps forward, Lucas changes his stance moves forward and places his opposite foot behind the opponent’s foot, to trip him. He then blocks the hip with his other arm as he pushes the opponent down using his shoulder.
