Rude explains what to look for, before doing the double-biceps pose. But, even Gorilla Monsoon says that Rude's biceps don't have that much peak to them.
Interesting!!!
"You never saw Arnold Schwarzenegger pound his chest and jump up and down, when he won Olympia!!!" - Jesse Ventura.
Pumping Iron drawed a crowd because it had the charismatic and body-beautiful Arnold Schwarzenegger in the lead role of a docu-drama that didn't focus solely on the prejudging or finals of a contest. It had drama that LEAD UPTO the finals, and that (apart from the classic 1970's physiques) made the contest part much more watchable. Did I mention Arnold Schwarzenegger was in the lead role?

This WWE show drew because it had two already established megastars who were aesthetically pleasing and again, had drama - the posedown and matches that they had at the time. Rude was known as a ladies man, Warrior as a nut job, and both had amazing charm, charisma and personality.
Tell me, how does bodybuilding fit into this again?

What bodybuilding has is the free posing routines. People love that. It's the prejudging that they find boring, unless you're a hardcore fan.
