I would recommend the FIRM Parts Sculpted Buns, Hips, and Thighs video with Tracie Long. This has always been one of my favorites that I still include from time to time even though I am almost exclusively a Cathe exerciser now. Even though "Abs" are not mentioned in the title, they are definitely worked throughout the video. As a matter of fact, she begins with abs as a warm up. All of the leg work is on the floor which I also love for those days when I just can't see myself lunging and squatting for an hour!
