SHAPE, I agree twith ya about the number of GetBiggers who enter a gym on a regular basis, but I'll raise your twelve to at least a 20.
And of those 20, less than half serve as competitors or in some arena within the bodybulding world.
Years ago there may have been more, but most were run off by those GetBiggers who never saw the inside of a gym nor lifted anything heavier than a vacuum cleaner.
There are an exceptional few such as Go4 It and BeThere and a small handful of other brave individuals who manage to put up with the shit that is tossed in their direction by the 'Vacuum-cleaner-lifters" and the "Never-saw-the-inside-of-a-gym-Jimmies", but that's been a part of the game since Herk tore down his first Roman temple and got blasted for doing so.
But believe it or not, the haters contribute to the popularity of bodybuilding more so now than any time in the past except for the Hercules episode.
Those on the verge of knowing everything say that it's just a simple matter of jealousy.
