I have been using this video 3 times a week for the last 3 months and am very pleased with the results. I still find the workout to be a challenge, so am not tired of it as yet. I like how it combines stretches, flexibility, aerobics, and strength training all in one video, so that I don't have to change tapes. As a 63 year old, I also appreciate the combination of standing and sitting exercises. I would recommend this to a friend if they don't mind being taken back into the 90's world. Three friends and I work out together which probably helps us stay committed to our workout.
