Firstly I'd like to apologize for asking so many questions. I seem to have hit a bit of an inquisitive stage this week. There are pros and cons to both techniques, for example in the hands of a martial artist who knows how to strike the punch can be quite deadly, but just the same if those fragile knuckles ( assuming one has not endured iron palm training ) collide with the skull, it will cause damage or even break your hand. Palm strikes are safer but also slower and have less range. That are also unnatural to most people. Obviously there are situations where one is more effective than the other. For example if you were trying to deescalate a conflict but your opponent swung on you anyway, smashing your palm into their face is quite a simple and natural task. But what of after? If the fight is prolonged more than those first few seconds of your initial reaction. One thing I have noticed is that in most forms/katas I have see/performed, punches are usually aimed towards the imaginary enemies torso area. Some go towards the face yes, but the stance and motion of the punch usually is striking towards the body. Does that mean anything? Appreciate your thoughts.
