My Knees are on Fire

So I got an Elipticall Exercise machine yesterday, and I was working out on it today and WOW my knees are on fire I usally go for little walks and jsut do laundry during the day and oh my I got on that thing and thought I was gonna die, but hey a little at a time. I started today with ten very long minutes at my own pace adn then tomorrow I will up it to 15 minutes at my own pace and then maybe in a couple days after I get use to it some more I will up the speed but I like it. I am not trying to loose alot of weight I am saving that for surgery all I am trying to do is tone up for after surgery so hopefully I can iliminate a plasctic surgery. Did anyone see Dr. Phil I was working ou****ching it and my heart goes out to that family. I understand what she was saying about loosing the twinkle in your eye and giving up because there was definetly times I gave up. And then I found all of you and the WLS and now I can live again with that twinkle in my eye. So Thanks again to everyone Big hugs April
