Carole, I saw that you were online and I was sooo hoping to hear from you. Thank you! I don't have any knee problems either. Actually, I had a bit of a right knee problem before I started Cathe and now that I have done her religiously, I never have any pain in my knee---I am guessing that her workouts have strengthen my knee, if that is possible (?). I won't be concerned about it now. Thanks again!
Kate
