imho it would be better to slightly resize the "book picture" on the left. the huge size gives me the feeling of also being an ad, thus as a new visitor I'd ignore it. and maybe move the "best of sl.com" section up one place, so people find the link to the 5x5 program quicker. I know that screen resolutions vary, but mine for example (1280x800) doesn't even show the recommended products part on the left. and studies have shown that people still quite often do not scroll (sorry, no link).
this study shows how people read websites, here the home & blog page fit perfectly. I think somewhere on that site they also explain that most internet users simply ignore banner ads.
what I find slightly disturbing is that the ads are often promoting exactly the opposite of the SL approach (e.g. gain 41pounds of muscle in 6 weeks, firm and flatten your abs, get six-pack abs, etc.), but I think you cannot influence it that much.
with all those colorful pictures on the top and right, the logo somehow gets lost. those pictures somehow outshine it, if you know what I mean. I would even go so far and say that the pictures steal the viewer's focus by being so much more present.
taking away that obtrusive ad on top would imho look better. probably even enlarge the logo a little, making it more prominent.
please take this as constructive criticism, I really appreciate the work you put into the site. and I do understand that the ads are a necessary evil...
