I used C25K two years ago and almost completed it, but I got really sick and couldn't, then I started running at the gym and lifting to help look good in my bridesmaid dress at my sisters wedding. Lost a total of 12lbs and looked amazing! Then work got out of control busy and I got lazy...stopped working out, stopped running and ate like crap and gained it ALL back! Now I'm ready to get back into shape as if I have another wedding to be in! W1D1 done today!!! It was 85 degrees out but I completed it, sweet and all!
