A good front kick comes in handy. For all those that are playing at home, #6 is a front kick. Variations include thrust, downward thrust, snap, instep, etc. Targets knees, bladder, hip joint, ribs, solar, etc. There is no arguing that this is a MA staple in every system. Oh, and I have used this as well in a confrontation many years ago with a clown trying to box me. He didn't want anything to do with me after that.
