i have to admit i have not watched/used it yet.  but i have been in physical therapy for 3 months now (for my pelvic floor) and it is working great.  i bought this and let my pt watch it - she said it is a great video to use.  but a warning from me - going to a pt gives you specific feedback on what you need to fix vs. a video that can't tell you what your real issues are.  there were many things that i thought were fine with my body that weren't and vice versa.  THIS CAN'T REPLACE A REAL PT. i am going to use this after i am discharged to keep up my exercises.  My advice it to see a PT first, then use this to reinforce your treatment.
