However, Immi's principles were applied on deeper level by Eli Avikzar and myself. In fact I created the concept of Sequential Execution by identifying the classification and naming it.
Well If your tactics are like most boxers, you can apply the simple side step concept. But in depth, sequential execution dictates that either in the short range when you lunge, or in the long range if you wait for the opponent to get closer, you should not consider executing a side step not until your arms or upper body finished their role in your planned move!
Simple distinction in terminology where appropriate, is important for professionalism.
Bombardment with terminology never does. A distinction in explanation and drilling methods that get the job done faster is always welcomed if it helps to get the job done faster.
Training new recruits in a fast pace environment cannot afford loss of training quality time. If you just let people spar without trying to program them to be efficient, you never know where it will end. You have no control on the results until you see performance.
You also need to identify what you are looking for as well. If people sparred and one won, it only means he was able to apply either his natural ability to sort out fighting methods or natural instincts, over his opponent’s ability.
But if you are looking to prepare someone for the unknown, you need to know every method, possibility and option so you can sort it out and have your plan in place.
Then you need to sort out a plan to teach your students. While side step alone can be applied with timing to re position your body out of your opponent’s line of attack, and then you can follow with counter attack, it is crucially important to know that most of the times, it cannot be done with the constraint of reaction time.
If your opponent’s attack can be predicted leaving you enough time to react, you can do it. But in the shorter range still not too close so you still have reaction time, it is important to do a deflection first instead of a sidestep, or move your head or torso first and with this motion of head, hand, or hips, trigger a chain of reaction that drive your body with gravity to a side step.
If you never teach it and never think of it, your success in executing your self defense or Krav Maga techniques is dependent on your ability to over time grasp this concept at least on the subconscious level.
If you are lucky, you can defend yourself, but if you are a Krav Maga Instructor, that should pass proper training to your students, they will probably struggle for a long time to be able to apply their techniques.
While many Punching and Kicking methods use a simultaneous whole body muscle tightening, or whole body weight shift with strikes and kicks, Pure Krav Maga chooses sequential execution recognizing there is more efficiency and effectiveness letting each body part keep its optimal speed without slowing down to adjust to a heavier body part that takes more time to move. That way you get maximum use of acceleration of each body part and synchronize it to maximum impact. The same concept is applied to evasive defense moves.
