too much motion

I saw in a photo magazine that you can blur a background and have a moving object by focusing on the object and moving the camera along with the moving object, keeping the object in focus, and allowing the background to blend together. This was an attempt at doing this using the continuous photo option which takes pictures continuously every second or so until you wish to stop.

Instead of my subject, Torrie, being in focus, both she AND the background are blurred...I'll have to work on this some more.
