Regarding exercise, I am to looking to see how I can exercise my
          cardiovascular system.

          At lunch, I go outside and ride around in my wheelchair but, as
          you know, riding around does not get my cardiovascular system
          pumping.  I asked my doctor to search for me for a exercise bike
          that only has the front system.  The reason why I want this is
          because then my wife and I could both use the exercise bike.

          If anyone on this listserv could tell me such a product, please
          do.  My doctor is searching her sources but nothing yet.
