Professor Lucas Lepri demonstrates a footwork drill to counter the Single Leg X-guard or butterfly guard by using a strategic foot hook on the leg. As the opponent attempts to secure their hooks, Lucas bases his hand and executes a circular motion to place his foot hook over the opponent's leg. This allows him to center back up. To maintain balance and leverage, he shifts his head to the opposite side of the leg he is clearing. Once the hooks are cleared, Lucas immediately transitions into a sharp knee cut to bypass the guard and secure side control.
