question on posing

[Naturally Low Octane]

ok guys, was looking in some muscle magaizines today at work (as i do EVERYDAY), and i happened to pick up on something i had never noticed before. why is it that in 90% of the poses the pro's are doing, the thumb is curled inside the fingers on bicep flexes. naturally the tumb is outside the fingers to me.

It's just posing protocall, the judges find it more asthetically pleasing with the thumbs in, with them out it takes the eyes away from the muscles being flexed.
