As always, I also publicize my article in DeHaan Services ("Battling the Delayed Onset Muscle Soreness Syndrome").
I re-used the image from a completely different article specifically about running a marathon. At least I had the grace to mention marathon running in this new article. Writing tip: it saves time if you can re-use an image.
My inspiration for this article was a science/health report on delayed onset muscle fitness; then I quickly realized I could add more to that author's points. Writing tip: be aware that you may be able to add your own background to anything you read or learn, and thus create a new, viable and worthwhile article yourself.
