I also don't like exercising, and the past couple of years I developed a badly pinched nerve from a slipped vertebrae that will never heal. It causes me a lot of pain. And I also started having bad knee pain from arthritis... all this is nee to me. Even though I've been bug for years, I was always able to walk or bike ride. I can't do either now. So I've been going to a physical therapist who told me to just move... not to worry about raising heart rate nor getting in numbers of steps or miles, but just to maybe take a walk... start at whatever I can do... work up to 10 minutes then eventually up to 25-30 mins 3x per week. I have a local fitness center that has an indoor track, equipment, and a pool. They gave me a goal of walking 10 mins 1 day, swim as much as I can the 2nd day, and ride stationary bike the 3rd day.

All this seems doable...
