Both my knees have been very painful for over a year now so a visit to the GP led to an x-ray and off to the consultant. I have been told that the cartilage in both knees has worn away. I am only 44 and need to lose some weight to lower my blood pressure but obviously can't walk far, certainly can't jog, unfortunately can't afford to go swimming. I need some good excercises that I can do at home for my waist up I suppose!! LOL!! Hope someone has some ideas for me
