I applaud you. I never wanted to before, but I want to run now. I am walking on a daily basis. I have seen a few "couch to 5K" sites, links, or tips. Maybe try a google search for ideas. I did see somewhere that the first few weeks just walk fast 5 minutes and cool off walking slower for one. Then increase, but I don't remember the increments. I am working with my cardiologist to be able to do more, so mine may be extremely slow. Have you consulted with a doctor? I am sure like me, they tell you all the time that you'd feel better if you lost weight. But if you go in with a plan and ask for help, most doctors will help you figure out the best route to health. I wish I had done that at 24 instead of 35.
