I had a physical therapist and after doing almost the same exact exercises after 7 sessions I decided to quit and do them at home. I do lots and lots of research and walking has been touted as the best thing you can do for hip replacement therapy. If I hadn't read it over and over and over again I would not be doing it. My surgeon approved my going on the treadmill as long as I did not overdo it. My surgeon knows what he's talking about. I listen to him not the physical therapist.
