His back lacks denseness and thickness. Looks flat and stringy.
I posted this shot in the Morgan Aste thread. Not to scale, blurry, etc. but at a glance seems to bear out what most of you guys are saying. My crappy bro-science would suggest that he might wish to try some of those Yates-style bent-over(ish) rows with the underhand grip. (The one all us old farts started doing when Dorian first appeared cuz we thought it was 'the answer' LOL!)
