You learn "ways" to move your body as you develop, usually from the culture you're a part of. Through relaxing the body completely, and moving through your full range of motion consitently with a certain way of moving, you relearn movement.
That's part of what Wong Kiew Kit meant when he said that forms are the crystalization of thousands of years of practice.
Of course, if your exposure to gong fu is to psuedo martial arts, that wouldn't make sense.
However, the general aim of gong fu is self preservation and expression. Fighting is only part of what "self preservation" entails. Not falling on your head, if you fell out a window, transferring your weight in a more controlled fashion in your daily tasks might be another example.
