Hey FriedGREEN a lot of people can't do the elliptical because of their knees. We spent a lot of time trying to find the right one for us, most of the salespeople mentioned the knee issue...we wanted an elliptical or treadmill. Anyway, we got a real nice elliptical but after awhile Angie said it just hurt her knees too bad. My knees were fine, but I have some rotator cuff issues and shoulder problems from work, i used it for about 5 years but it got to be a little difficult for me with the arm motion. My daughter loves it so we gave it to her and her husband and bought a treadmill.

I hope you get things figured out.
