Three lines of attack.
The three lines of attack, this is probably one of the easiest concepts to get.
For such a simple concept, understanding how to utilize this idea pays huge dividends because there is always one line open to attack, recognizing this open line, or even anticipating this line to open up puts you one step ahead of your opponent.
This is how you sector the three lines, get a piece of paper and draw a stick figure, the body is the center line. Now draw a horizontal line under the head and another across the belt line. That’s it!!! You just sectored the three lines of attack, the high line (head) , mid line (belly), and low line (groin and legs).
This is a great way to start to develop combinations, for example, punch the head, punch the body, punch the head, that = high, mid, high attack another combo would be kick the leg, punch the body, kick the head, = low, mid, high attack, this is a combo you might see in a karate or a kickboxing match. You can use any of the 12 weapons of the body to attack single or in combination to any of the three lines of attack..
With this concept what your doing is building a battle plan utilizing sectors, again “science of movement”, moving from one line of attack to another searching for an opening or a weakness in your opponents defense.
By observing footage of your opponent or feeling them out on the spot you can analyze how they move through ranges, and defend the lines of attack, once you see their weakness you build a plan to attack it and visa versa, you can see what lines “they” like to attack and build your defense accordingly and prepare for a counter attacks.
In essence this concept you have just formed can resemble a grid with a center line and 6 sectors, three on the left and three on the right, you can add the info provided on the past threads and use your heavy bag as your personal lab rat to develop your own way of movement.
For beginner or advanced going beyond the fighting aspect and learning a formula to grow can give you tools even when you grow old and fat because the science of movement is first in the mind (theory) and then the body (the practical).
