Beth,
I preordered for several reasons also. First, I also wanted to take advantage of free shipping for Terminator, the only DVD of Cathe's that I didn't have. I ordered all three new workouts, because I think it's good to have some easier workouts for times when I'm not feeling that great, but still want to workout (I could have used them this weekend!). I figure that the beg/int weight work can always be more advanced just by going heavier. Also, I think I just want them all!
