Thanks Duckie for the advice.  I have had a knee and this is my second
hip.  On the knee, I had to go to physical therapy which was torture.
On my previous hip, I did all the exercises given to us in  the
physical therapy sessions we had at the hospital.  On my previous hip
surgery, I simply did the exercises on my own at home and it turned out
fine with no problems.  I did not use the NuStep on my previous two
surgeries.  This is a great piece of equipment for physical therapy and
cardiovascular exercise, but unfortunately not all physical therapists
have this piece of equipment and not everybody has access to a health
club with one.  I will check with my physical therapist and/or doctor
tomorrow.  Thanks, Dana
