Query: Helped me lose

Yeah, the movements get kind of repetitive. But, I think the 4 mile from 1993 is one of the best. Using the fitness goal chart she gives for miles to walk per week, plus doing additional workouts of your own on the side does wonders. I lost 20 lbs. in two months, until I had a surgery on my arm. I couldn't have felt much better. I was eating healthier too, so this helped also. Key is consistency, and do more than required. I lost a total of 45 lbs. in four months all together doing her video and other physical activity. Somehow I lost the video when moving home from college. I found it recently, and it is going to be put in effect immediately:)
