The program has worked super well for me for over a year. im 82 W/ arthritis in various areas of body and L 2, 3,4, 5 arthritis .... sciatica. Spine doc says too far advanced for safely doing injections or surgery. He doesn't see how I'm functioning as well as I do. I do ..... God is holding me up and this exercise program. I have gone thru the Foundation Program and started over plus the therapy sessions as need. Your exercises pretty much follow the physical therapist's recommndations but with this no appointment needed and this is at my finger tips. THANK YOU
