If you only want to learn techniques suitable for self defense or combat you are wasting your time if you are taking a
martial art. Do you ever train a punch pulling the opposite hand to the hip? Would you do this in combat or self defense situations?
What is the stipulated purpose for whay you practice 1 step sparring in your system or gym?
The failure of a technique under certain circumstances may teach how the technique needs to be used to be effective. Once a technique is learned in a static environment dynamics such as moving off the line of the attack need to be used while executing the technique as well as different stuations. An empty hand attack can be a substitute for a weapon attack.
Let me ask a question? So you believe that martial arts training is not suitable for self defense? Did I read that right?
Let's just say your take shows the imperfection of written communication. Saying that if you only want to learn techniques suitable for self defense, learning a martial art is a waste of time does not mean martial arts does not have self defense techniques.
The first big issue is that before a meaningful discussion can be had is that people involved in the discussion must agree on how terms are defined. Otherwise it is like trying to have a meaningful discussion while the participants speak a different language.
There is no real consensus about what is and what is not a "Martial Art" An example I often give is some 25 years ago I met an Israeli who had been in the Army if he had learned the Martila Art of Krav Maga? He said "What "ART", there is nothing artistic about kneeing someone in the nuts."
Peyton Quinn of Rocky Mountain Combat Applications training will often state that he does not teach Martial Arts.
So, my point was really that there is much more to what we typicaly consider "Martial Arts" than Self defense, and if all you want to,learn is self defense, why waste your time learning all the other stuff?
I supply the following link as afood for thought toward what is and what is not a martial art versus what a discipline geared solely fo combat might be.
