How can an article publish in a health magazine?
You need to “query” the magazine. Find out contact info (usually the name of the fitness editor). Then you need to search how they want to be contacted (most prefer e-mail). Write out a letter (make sure your grammar and spelling are perfect). Explain your idea for an article and why you are qualified to write it.
