Whether you call it "cross-training," a "hybrid approach" or "mixed martial arts," your goal is clear: to diversify your skills by adopting techniques from other styles of fighting. And to anyone with experience in the martial arts, your reasoning is equally clear: Because nothing is perfect, all systems of combat can be improved. Throughout the history of the martial arts, many masters have recognized this. Bruce Lee was one of them. Sensing the shortcomings of his original art, he studied other styles from the East and a few from the West. He learned new theories and techniques and tested them before creating what's now regarded as one of the premier fighting systems on the planet: jeet kune do. Another pioneer was Imi Lichtenfeld, founder of the Israeli art of krav maga. He developed his system for survival on the battlefield. Like Lee, Lichtenfeld researched various fighting arts and extracted what he believed would be the most relevant for his soldiers. Over time, krav maga developed further, making it functional for police officers and civilians. The newest pioneers in the martial arts are Brazilian jiu-jitsu practitioners. Using the methods the Gracie family learned from a Japanese judo champion, they created what's arguably the most effective grappling system in the world. Can these three successful hybrid arts be improved? Of course. While you're reading this, experts in each art are probably analyzing and fine-tuning their methods. Because my expertise is in wrestling, I'll leave the analysis of JKD and krav maga to others and concentrate on what I know — specifically, on how American wrestling can be used to augment Brazilian jiu-jitsu.

Now, suppose someone, particularly someone for whom English is not a native language, hears me say, "Ehh, howzit?" to a friend and decides it is the way a reasonably well-educated, upper-middle-class person greets others. After all, they heard me say it, and I make my living using words. Therefore, it must be correct.
