Hi:
other instructors you could try to learn with include Karen Voight, Petra Kolber for Reebok, Gin Miller's Power Circuit might suit you nicely, the moves are athletic, you can vary the intensity depending on energy levels and fitness and it's very easy to learn. Try also Charlene Prickett. She's very straightforward, chatty and gets the job done. Keli Roberts is another good chcoice. These instructors would help you learn stepping basic moves and vocabulary and build a foundation of fitness. See 'www.collagevideo.com" for tapes by all these instructors and customer reviews. You can order a paper catalog from them also.
After that, I would reccomend Cathe's Step Heat as a beginning Cathe video.
Good to have you on the forums and best of luck. Let us know how you get on!
