Kathy Smith's 2 on 1 Workout provides two very effective, traditional aerobic-workouts. I am a huge fan of Kathy for her various professionally made excercise workouts and her pleasant personality. These workouts aren't disappointing in that sense either. The problem with this 2 on 1 video package is that the videos were originally released in 1984 and 1985, not in 1994 as the video info lets you believe. This means that the movements may be a little old-fashioned and the 80's disco music is terribly annoying, and for me it's too much to handle! If you don't mind the music and the 80's settings, this package is a good buy. I, however, will concentrate on Kathy's later releases that are packed with more recent scientific information on fitness and are more pleasant for the eyes and ears.
