I'm in my sixties and have got osteoarthritis in my knees and, to a lesser extent, my hips. I'm dieting to lose weight, which is going well and also want to increase my fitness level, as I'm quite sedentary. I enjoy my Wii Fit, but do find that some exercises are rather hard on my knees. I just wondered if there were any other exercise DVDs out there that people had found useful and which were suited to arthritis sufferers. I do prefer to exercise at home.
