Sharla,try to isolate your hips.Dont throw any punches,just isolate the movement of how your hips should be moving in to the shot.
In theory there should be nothing interesting there,but Im pretty sure Chris and I were both thinking in terms of training a male boxer.
Now my methods have worked for Fuer,but she may be the exception,not the rule
Id be curious to see how it feels to you,when your isolating,as one of the major diferences(other then the pretty damned obvious ones)between male and female fighters,is the hips,and their angle.
