His right triceps is shot.
I feel sad for Chris. I mean, dude's the last (basically) from his particular era still jonesing for pro competitive glory. Then again, he wasted a LOT of time during his prime years, so I don't feel too bad.
Would love to know what's going on in his head.
He should hang up the suit and leave his stage success as is so as not to tarnish the memory.
P.S. Sounds like what the majority of pro bodubuilders should do.
