Target: A pressure point known as jahng moon. “It’s located on the lower part of the rib cage,” Suh said. “Hitting this area is very effective. It’s doesn’t make the attacker feel like he just got a concussion like some of the kicks, but it’s very serious. You can easily break a rib, which will make it hard to �ight, hard to breathe and hard to stand. He’ll probably be recovering on the ground.”
Tool: The bony part of the knee, ideally the kneecap. “The knee and the elbow are the strongest natural weapons a human has,” Suh noted.
Tutorial: The knee strike is versatile enough to work against a variety of targets. “When the opponent is standing upright, the knee is perfect for hitting jahng moon because the point is low on the ribs, and that makes it easy to reach with your knee as your knee is moving upward,” he said.
The solar plexus is also a valid target for a knee thrust, Suh said, but it’s higher and it’s on a vertical surface. “That means if you want to hit it with a rising knee, you’ll probably have to bend your opponent over,” he explained. “Angle is very important when attacking the solar plexus.”
To enhance his effectiveness with the knee strike, Sung Jin Suh grasps his foe’s uniform and pulls him into the technique, but the pressure point on the ribs that’s being targeted also can be hit while the opponent is standing upright.
