Well, I'm on week 2 now of my Couch to 5K program. I've never been much of a jogger, but I think I can handle this. It starts of easy (run 60 seconds, walk 90) and takes about 1/2 hour out of my day. I've been doing it at lunch with a co-worker (insert a "that's what she said" joke here).It starts of slowly like an old man lowering himself into a bathtub and the running intervals get longer
