Like MAXX said in another thread it's very prominent on Phil. After a certain age it suddenly disappears on a lot of guys. I saw some speculate that wide grip pulldowns wears it down over time, _bruce_ thought it was a neck issue.
I had the best results for the brachioradialis when I started doing 20-30 seconds static holds on single arm reverse curls on the cable machine or with a very slightly cambered bar (not that stupid gimmick bar Strict Curl Nation uses).

Flex Lewis:
Sick build. I know he's short but his lines flow well. Dallas McCarver trained at Flex's gym the last day that he was alive. The next day Flex saw his gym bag and gear in the gym and he lost it. Dallas had a lot of potential and came second at the Arnold behind Cedric. Cedric ironically also passed. Rough industry to be in for some!
Lewis had a truly insane looking physique!
Looks like Derrem’s biceps were actually bigger than Phil’s in that picture
Where do you do the static hold, midrange?
