Core DVD

mandie919

I am looking for some advice. I currently run or do some other form of cardio for about 45 minutes a day/6 days a week. I am looking to add some sort of strength or other workouts to my routine, specifically for the core. I would like to continue doing at least a half hour of cardio a day so I am looking for a DVD or workout to add to it that is about a half hour as well. Any suggestions would be greatly appreciated!
