Knee

From FightWiki

The knee is a powerfull hit. When you shoot a knee, try to bring your ankle all the way to your butt, making your knee strong and pointed. Thai clinch is a great place to use them in. Try to either hit your opponent in the head, thys, or mid section. To block a knee, either try to back away, or never bring your face down low enough to be hit by one. Or in a clinch walk into the legs, closing the distance.
