I've been thinking more seriously about running. I have had bad knees for a while but they are getting better and better the more weight I lose. I think I am going to start with Couch to 5K (maybe a few months from now) and once I do that, move on to the Zombies, Run! app. I'm not good with doing smart phone things and moving at the same time either, but I gather this one is pretty simple.
