I have Xtreme Timesaver and Crunch-Free Xtreme Abs. Not a huge fan of both of them. The moves are just too fast for my liking, and even when I slow them down, I find them a bit awkward. She is not an instructor I stuck with. IMO, Jillian's video's are WAY better (Shed & Shred is awesome). Cathe, of course, surpasses them both.
If you like Jackie, I don't mind swapping the 2 DVD's I have for something of yours, straight exchange. PM my account if you are interested.
