why is there only one low impact program available? i tried the fb30, but it is just too brutal for me. i love the idea of a program so i don't have to come up with my own routines, but really don't want to repeat the same one over and over. is it possible to tell what levels the other programs' videos are at? how many low impact there might be? i have loved this sight for a long time but am discouraged with the fact there are many routines i can't do physically. please help those of us that are battered and beaten but not down.
