Punching Technique (Jirugi)
Punching is executed in various ways according to the tools listed below and the position of the opponent.
Forefist
Basic principles:
Clench the fist firmly at the moment of impact so that it acts as a hammer instead of a cotton ball.
Punch from the hip to the target at full speed using the shortest distance.
Avoid unnecessary tension of the arms and shoulders.
Pull the opposite fist simultaneously to the hip as the punching fist moves out.
Relax the muscle immediately after the fist has reached the target.
Keep the back straight at the moment of impact.
Do not pull out the shoulder at the moment of impact.
The fist must turn a full 180 degrees at the moment of impact; i.e. a corkscrew effect, with the exception of vertical and side punches.
The back fist must fact downward when the fist is pulled to the hip.
The rear foot in all cases must be placed firmly at the moment of impact to contain the rebound.
(All punches throughout this book are considered front punches unless special directions are given.)
Correct
As mentioned earlier, revolving the fist and concentrating the muscles of the hip and abdomen to a small area is a very important punching technique theory. The farther the distance between the target and the fist, the more this theory applies. The hip is the most suitable and natural spot for placing or withdrawing the fist in the course of training in the case of a front punch with a single fist. In actual combat, however, a certain amount of latitude and flexibility must be observed.
Incorrect
The fists have failed to revolve.
Left back fist faces upward instead of downward.
Walking Stance Obverse Punch (Gunnun So baro Jirugi)
Walking stance obverse punch is delivered from the same side of the leg that is bent fully.
Side View
Front View
Right Walking Stance
The fist must stay in the centre of the body at the moment of impact as far as front punch is concerned. The same principle is applied to the middle and low punches.
