Great Exercise For Arthritic Knees

I have severe arthritis in both of my knees, and my doctor recommended that I start walking to lose weight and hopefully ease some of the knee pain. I live on a great big hill, and to attempt that hill both ways would be too painful. I looked online and checked exercise equipment ratings, and bought the Sole F80 Treadmill. I have it in my study, and I can watch my television shows when I’m working out. I’m losing weight and my knees are slowly improving. I’m even able to walk around the stores and mall without having to sit on the benches. I’m making good progress!
