Whether you are Boxing, rolling in Jiu Jitsu, or Wrestling on the mats, speed is a factor that can destroy, or enhance your training depending on how you use it. Here's a quick rundown on the benefits of controlling speed to enhance your training.
Effective Strike (Xiao Da), is the Chinese principle of striking to vital targets, or targets that have more destructive impact than other areas of the body. This is a common concept in many styles of martial arts. I recall the first time I showed up for Tae Kwon Do/Hapkido class back in 1991 - my teacher said - "Want to kill a man? Hit here, here, here, or here." I was happy, but stunned.
You charge in on your enemy, filled with the hope that you can capitalize on that weak spot you spy in their guard. As you are about to land your punch, suddenly, without warning, BAM!!!! POW!!!! SMACK!!! His strike has met you mid-stride and square in the nose. As blood begins to rush down your face you pause and wonder, why you were unable to hit that giant hole that invited you to enter to begin with?
