Hi there...start very slowly, be consisent, and don't push yourself to hard. I was in the same boat with you and a few months ago I started out with a 5 minute walk around my parking lot at work on my break. But...I made sure I did it EVERY day, when that got to be really easy I added a minute or two at a time and so forth....now I am easily walking 17 minutes with no pain, plan to stay ther till it gets to easy then progress....hope this helps, keep us posted, we care!
