Chin-na is a Chinese term used to describe grappling techniques that work by twisting or applying pressure to specific joints, muscles or tendons. Instead of targeting the most common acupuncture points, its techniques typically focus on accessible targets like the limbs.
After mastering chin-na, you won’t have to directly grab any pressure points in order to control your opponent. Instead, you’ll be able to manipulate your opponent’s nervous system by applying pressure to your opponent’s weak points. The more he struggles, the more it hurts, making him his own worst enemy.
For those of us who don’t use chin-na, there’s good news: Its practitioners usually do not target vital points because they seek to control their opponents rather than maim or kill them.
