It's been a while since I have been to muscle show, but
when I was regularly attending, for competitor posing,
I can't recall seeing a better poser than Ed Corney.
Having said that, the best poser I have seen would be
Russ Tetso, which is more "performance" rather than
competition, though in the physique department, he was
no slouch. I have seen him several times as a guest
poser. Outstanding presentation.
And not that your asking . . . probably the worst pro
poser I can recall seeing was Sergio Oliva. His physique
was mind boggling. But the disparity between his build
and his posing ability was huge, with his posing leaving
much to be desired.
