Give yourself some time! Cathe's videos are a blast once you get the footwork down. It's always best to preview the video at least one time through before actually working out with it. From there, you can usually practice or keep rewinding any sections that you find confusing until you feel more sure of the footwork. I have to say that I have a lot of step videos, and Cathe is absolutely one of the best if not the best at giving clear cues and keeping movements choreographed with the beat of the music (I hate when an instructor has a rushed movement which doesn't really fit the music.) Having recently started a running program, I find myself really missing my Cathe cardio workouts (though I get to lift weights with my Cathe weight DVDs)! The thing I miss the most are the moves. They make time fly!
Again, give yourself some time to adapt. I remember thinking certain tapes were very hard to learn, and it was such a blast to come back to them and find myself relaxing and enjoying the choreography because the moves had become MUCH more natural. What's that they say -- muscle memory!
Take care and good luck!
