The beginning Callanetics is a good intro...I did not use it myself but have watched sections on it...each one of her routines are good infact..she does a lot of explaining and has modifications that can be done for specific problems...it is a good idea to watch it first, there are some exercises that people with knee problems shouldn't do..the pelvic tilt, rotations, and wave I think but I have been able to incorporate some of them...she is so calm in her direction to and seems to just know when you are going to tighten up something or shift your weight the wrong way and reminds you to shift back and relax...the next step is the AM/PM tape...the 10/10 is a big jump so you can do it just do less reps of things...I started with 65/100 but even less than that will help you get in the right positions. Good luck Denise.
