Hi all

I have been thinking about the one-inch punch. Is this specfic to chinese martial arts or do other styles use it as well?

Has anybody ever experienced a one-inch punch(OIP), I mean a proper OIP not when the person pulls back or pushes you both of these I have seen as martial artists pretending they can do the OIP.

Can the principle of the OIP be applied to other parts of the body? I know it can be done with elbows and knees. but anywhere else?
