Content Writer for Fitness Blogs

I'm looking for a virtual assistant that will write articles for a few fitness blogs that I own. It will entail finding videos online at youtube and other similar sites and posting it to my site. Then write a 25 word or so blurb about the video. It will have keywords in the title and content to help with seo. It will also entail just writing articles related to working out, nutrition, fitness, supplements etc.

I prefer to have someone who is inot just a writer but is into fitness themselves.
