Hey, Laura, I don't know much about hese wokrouts, but I thought I'd let you know that I checked out that Tracie Long Training website and the Core video looks like what you are looking for. All exercises are done on the stability ball and it's more then just your core that you are working.
I know that I'm very intersted in these workouts now.
