Punching power is something that everybody who enjoys physicality wants. It is something that allows a person to dominate another male, which in the reproductive world is seen as competition for females. We see how people worship athletes. It is something ingrained in our biology to want to be physically superior.
In the boxing world, they say punching power is genetic. While punching power potential is heavily influenced by genetics, the actual power can be trained up to the point of reaching your potential. The most important thing is proper technique that allows for generation of force. Some untrained individuals will naturally know how to incorporate their body into their punches than others. There will be females that can do this too, and some females will naturally punch harder than some males.
