Lifting like he does is only asking for trouble. He supposedly a knowledgeable person, but yet lifts like this? He's either doing it for his ego (I think so), or because he lacks the knowledge to realize 1 rep is useless for a bodybuilder.
He is also a natural so he has limits, and since he doesn't want to take things to the next level (I myself trained natural for almost 20 years) then he should have just accepted where he got himself in bodybuilding before his injury.
Also after reading his own posting, seems like there were several doctors telling him that he didn't need surgery. Yet, because he thinks he knows more then other people, he opted for surgery. A total waste by looking at his photos.
If he was so worried, why not worry about adding some mass, instead of a little pimple on his chest.
