I think I've determined one of the reasons why Levrone's back usually is underwhelming. I know it's largely genetics/drug response, but it can't be dismissed that Kevin never seems to really contract his back when he rows. In all the movements he uses mostly short, choppy arm flexion.
Just an observation.
And yes, his wheels will be thin and lack the gnarly quality that only comes from consistently intense sessions over several years.
One more thing. Back in his day, his musculature always seemed "bursting". Now, despite fantastic development and shape, he no longer sports this attribute.
It's age. As a 46-year-old, I see this diminished phenomena (albeit on a much less grand scale) in my own physique. Mass is there (even more so) but the full, tight and bursting appearance is absent.
