Vitamins and Exercise

I've been pretty good on taking my vitamins, but not so good on exercising. I can still walk, but just barely. My left leg is still strong, but I essentially cannot lift my right. So walking, with assistance is essentially taking a good step with my left, leaning, and swinging my right leg around and forward. Walking has gotten harder and harder so consequently I walk less and less. I counted my steps for a couple of days and figure I average 200 steps as day. That is pretty low, so I have enlisted some friends to help me. Gary,Gord and Wayne walk me a few additional steps when we go for breakfast or lunch. When first starting this [last week] I got Gary to walk me 300 additional steps. It just about killed me. So, with everyone, I'm trying to do an additional 50 steps. I can do that fairly easy. Next week, or the week after I'll bump it to 75 or 100 steps. I told Gary my goal was 5,000 steps [a day!], but I now know that is unrealistic. But any additional steps are better than none.
