In one of Iain's articles about punching power he talks about the development of power. There is a line that states "Another common error is to twist from the center of the body so that one side of the hip travels forward whilst the other side is going backward". The article continues to say" to punch with power at close-range you should pivot from the side of your hip so that the whole body is travelling in the direction of the punch".
Is there anyone who can help explain the bit about pivoting from the side of your hip or have a video showing what that looks like. I'm not quite clear what this means.
