You need to change your header and also site looks more simple, so try to do some change over design and have some good Logo....
The font color on the protein powders page is tough to read, can you use white for the font, like you did on your home page?
You can use "Wordpress" to create good website. Wordpress has pretty free themes and premium themes. You can add videos, contact, about, etc ? Thanks, Megharaj
You should do something about your header make a better header to make your site more attractive navigation is good
it's very standart design you seem to re-design it to be look more pro and about the articles you should write it more, thanks
I'm not a fan of the theme. Sorry, I think it draws the viewer away from what they came to find. I would try to lighten it up a bit. Good niche to enter into though, lots of demand in the coming years for supplements and medicine.
i dont know whether your purpose of making this site is solved or not... try to make it more interactive...
do people really make money in the bodybuilding affiliate niche ? i'm of the opinion that anyone savvy enough to find a blog would just download an ebook for free rather than buying it through clickbank for a sky high price.
