I've been working out to floor and step aerobics videos for a couple of years and have just now seen all the "stuff" about Cathe's videos. I'm very intrigued and interested in getting started with these, however, as with so many others, I don't know which ones to start with. I also do strength training with dumbells. I don't do well with complex choreography. Which ones would you recommend for a seasoned video person, but someone who has never done a Cathe video? Thanks.
