This is a very early CIA tape. I think it's probably from the late 80's or early 90's, but I couldn't find a date anywhere.
It's a good cardiovascular workout, but it's not much fun. It's very repetitive, including the warmup. At the time the video was made, I'm sure it was better-received by home exercisers/instructors, but these days, there are so many more fun (and intense) workouts to choose from. Grade C+.
Instructor comments: Nancy is wonderful -- I wonder what she's doing these days. She has all the skills of a great instructor, including personality, cueing, and motivation. I'd like to see her make an up-to-date video.
