Walking is fine but a couple of miles of it and I have knee problems. I go to the gym and use the treadmill for fast walking at 6mph for 10 minutes at a time. Can't run due to that knee problem. A fast walk on a hill programme will stretch and condition the calf muscles and I have even pulled calf muscles on the treadmill. Ankles have hurt at the start of a "Lets get fit "again session, but this has worn off by the next week.
