Even with a bloody instructor in the same room as me , I still made mistakes and bad habits that I had to get rid of.
Try learning chi sau from a damn video or book , you might be able to approximate the shapes if your lucky , and it might even look like chi sau.
But like a fake Rolex watch it would just be a pale cheap imitation
Being able to use the correct energy , projection of the force vectors in the proper way and all the rest of it is something that can only be felt and learned in the presence of a qualified person and takes years .
This is exactly my point.
My instructor showed me a number of techniques that I was completely unable to reproduce until they were performed on me. It
looked like I was doing all the right movements, but the technique wouldn't work until I
felt how to do it. And you can't get that without a knowledgable instructor.
One such technique was the horizontal z-lock. I was mimicking my instructors hand positions, but until he did it to me and I could feel how the pressure was applied, I couldn't make it work on my opponent.
And that's just one example of literally hundreds of
basic techniques. There are
dozens of ways to strike with the hand alone, and that doesn't even take into account methods of execution such as thrusting, snapping, etc. Even once one learns the basic techniques, there are more complex combinations of techniques taught by many arts to teach application. Grappling is even more complex, requiring an understanding of techniques, leverage, resistance, angles, etc, and constant contact with a resisting opponent. There is so much beyond the appearance of physical performance necessary for effective application, and you can't pick any of that up from books and videos.
There's a reason professional athletes have coaches, and trainers. There's a reason professional football teams have head coaches, and assistant coaches, and quarterback coaches, and strength and conditioning coaches, and athletic trainers, and the athletes themselves have personal trainers on top of all of that.
If you could do it alone, and master it alone, people would. The arts weren't created out of thin air. Parker, or Presas, or Gracie, or Miyagi, weren't just sitting around one day when they were struck by inspiration. They had instructors. And those instructors had instructors. Today's instructors are the result of literally thousands of years of accumulated experiential knowledge. Sure, some people are creating their own arts, but by and large they fit into one of two realms. Those who have trained for years to learn martial arts and are recategorizing their knowledge for their students in a way they think will aid their learning, and complete jokers and frauds who are either delusional or opportunistic and are preying upon an ignorant customer base. Either way,
real martial arts are still being passed on by instructors.
Can an experienced student gain something from a book or a video, sure. But a beginner won't get anything of value from studying pictures of people doing martial arts, and certainly can't "teach himself."
