I'm guessing you don't have a treadmill. If not then I would suggest go to the store and getting a work out tape or two. There are ones that show you how to walk in spot and they kind of switch it up a bit so it's not so boring. Can you start going swimming, even just a couple times a week would be great. Swimming would ultimately be the best thing for you in your situation. Well, hope that helps a bit. Talk to you soon. Kristy.
