I am moving this to the Health and Fitness Forum where it belongs.
To get started running, you need just a few things:
(1) Good running shoes. BUY THESE AT A REAL RUNNING STORE. Do not try for a cheap option, you can really do damage to yourself that way.
(2) Patience. Don't rush it too much.
(3) Perseverance. You have to stick with it, don't quit. Starting a running program is alway hard and feels awful.... but after a while, running will become a joy. But you have to stick with it to get to that point.
I went from being a total couch potato (who could not run a mile straight without stopping) to running the New York City Marathon -- in just a few years. I love running now, but I sure didn't at first.
If you are really out of shape and not used to running, I think the best way to get started is to pick a distance -- say 2 or 3 miles -- and cover it every other day. DO NOT expect to be able to run the whole way. Jog until you get out of breath, then walk until you feel better, then run until you get out of breath, then walk, etc. You will find that you run more and walk less each time, and after a while you are running the whole way. That's how I got started.
