It is useful to watch clips of fights such as the brawls in the US on “Black Friday” when people attack each other over various sale items, and to watch scenes of police arrests; so you can study the physical dynamics of a real conflict situation.
You will notice that even police and security personnel, who are certainly trained in how to subdue a combative individual, usually do not handle the situation in an efficient, disciplined way
There is always a lot of clutching, pulling, shoving, grappling and so on. Most people, even the police, do not actually know how to fight.
Physical confrontations are almost always chaotic and haphazard; any training they may have received vanishes, and they act exclusively by spontaneous instinct.
This is why I do not recommend for you to practice complex martial arts techniques. Unless you are able to dedicate years and many hours a day to drill the techniques into your mind until they become reflex responses, you are likely to forget every move you have learned when you find yourself in a real fight. And, frankly, that is fine. You are not going to be fighting Jason Bourne.
Just practice two or three good punches, aim for the chin, and keep in mind five fundamentals:
–The body of the opponent follows his head
–Always move forward
–Stay off the ground
–Try to maintain distance
–Counter the opponent’s action with a complementary action, not an opposite action (if he pulls, don’t pull back; push. If he pushes, don’t push back; pull. This way you use his momentum against him)
