How to Learn Martial Arts "Pressure Points"
If you want to learn the pressure points used in martial arts, locate the most vulnerable parts of the body, including the eyes, throat, groin, and shins. For example, if you wrap your arm around an assailant's neck and press into their carotid artery, you should be able to lower the person easily to the ground. Hitting a person in the middle of their forehead, their sternum, or their temple can also disable them. Although you can use a training partner to help you locate these pressure points, do not strike your partner in these areas, as you can cause serious injury or even death.
Hit your opponent’s temple to disorient them. The temple is located 2–3 in (5.1–7.6 cm) behind and slightly above the eye. Striking this point on the body is painful, since it's one of the softest locations on the head. Use a closed fist or open palm to slam against the side of your opponent's head, disorienting them and giving you time to prepare your next move. This will also cause your opponent to raise their arms up to protect their head, giving you access to their body. The temple is so sensitive because it's the point where 4 different bones in the skull fuse together. It's especially dangerous to hit this area though, because the bone structure is weaker than other parts of the skull. Using an open palm can reduce the odds that you kill someone when doing this. Gouge an attacker’s eyes to subdue them and restrict vision. Spread your index finger and middle finger out 2–3 in (5.1–7.6 cm) and quickly strike both of your opponent's eyes with the tips of your fingers. As they raise their hands to protect their face, use your nondominant hand to either hold the back of their head, move their hands away, or strike another part of their body. if you keep applying pressure to your opponent's eyes after striking them, you could damage their optical nerves and permanently blind them. This is a good way to get away from someone if they're attacking you. They can't chase you if they can't see where they're going. Use a fish hook to control your opponent’s head and neck. To fish hook an opponent, slide your index and middle finger into the inside of your attacker's cheek. Then, pull on the skin at the side of their mouth while maintaining pressure to restrain them and keep them from turning their head. In a grappling situation, fish hooking your opponent will allow you to control their head and give you the upper hand on your attacker. You can snap someone's neck doing this if you pull too quickly and too hard. Try to avoid sticking your fingers in between your opponent's teeth while doing this. If they bite your fingers, the move could backfire. Punch or chop the side of the neck to make your opponent dizzy. When you find an opening, strike the opponent on the side of the neck, roughly 3–4 in (7.6–10.2 cm) under the ear where their neck starts to slope into the shoulder. This is the location of the carotid artery, which supplies blood to the brain. Hitting this location hard will disrupt your opponent's oxygen supply and cause them to become dizzy. This is the same set of arteries that you can restrict to perform a sleeper hold. If you damage this artery, your opponent could die. If you can't reach the side of your opponent's neck, striking them in the middle of their throat will make it difficult for them to breathe and will throw them off-balance. Strike the groin to quickly drop an attacker. The groin is a highly-sensitive area on the human body. Strike it with a quick kick or punch to send your opponent into a tremendous amount of pain. They will quickly drop to the ground, buying you time to flee or subdue your attacker. Your opponent will have trouble standing up after this, as attacks to the groin usually cause a fair bit of nausea. Punch or kick an opponent’s gut to bring them down to their knees. There aren't any bones protecting the stomach the way the ribs protect the lungs, which means you can strike an opponent's stomach and damage their organs without much resistance. Use a closed fist to punch your opponent's stomach right below the belly button to deliver a powerful strike that will make your attacker bend over. You can also use a bent foot to strike your opponent's gut if it's easier. Even if you miss the stomach, hitting your opponent's bladder or kidneys will have a similar effect. Slam an attacker’s sides to take the wind out of them. If you can't strike the stomach directly, opt to kick or punch an opponent's side, 5–6 in (13–15 cm) beneath the end of their ribcage. This will throw your opponent totally off of their balance while causing them to bend over to the side in pain. This is an excellent option if you want to reposition in a fight and gain the upper hand. If you need to flank your opponent when you're facing them, strafe 2–3 ft (0.61–0.91 m) with your dominant foot to your dominant side to keep yourself from needing to move both of your feet. Kick the back or side of the knee to drop your opponent. When you're in striking distance, lift your foot and aim the heel of your shoe at your opponent's knee. Kick it from the side or behind the kneecap to knock your opponent down to the ground. Because the knee is designed to bend forwards, it's incredibly easy to cause it to over-extend by kicking it from the side or the back. This is an excellent option if you're grappling your opponent and your arms are busy. Sweep your opponent’s leg if you’re lower to knock them down. If you end up in a position in a fight where your opponent is either standing over you or trying to force you down, drop lower to the ground and swing your leg through their shin or ankle to drop them to the floor. Swiping the ankle or shin is a great way to use your opponent's advantage against them. Swipe your attacker's leg from the side to knock their legs out or get behind the ankle to put them on their butt. Once your opponent is on the ground, you can either grapple them with your newfound advantage, or take the time to get back to your feet. Grip your opponent’s wrist and bend it to disarm them. If your attacker is holding a weapon or an object, reach out to grab the front of their hand with your dominant hand, and the side of their wrist with your nondominant hand. Once you've gripped both the front and side of their hand, bend their wrist inwards to cause them to drop their weapon after they open up their palm. With their wrist still held tight, you can pull their arm behind them to execute a wrist twist, which will allow you to subdue your opponent. You can break someone's wrist by doing this.
