I would recomend setting up a website directly related to your niche on tumblr, useing datafeder or woozone, a wordpress pulg in to up load affiliate products from amazon or any other place were you can find bodybuilding products. using and auto posting software like qplus (there are others) to post every 15 mins with you affiliate website link. I would recomed to for your website to have an affiliate store but also have some product reviews in your blog part of your website use iwriter to get some reviews writen for you for at lest 5 products, iwriter is pretty inexpensive. hope this helps if you need and further assitance skype me
