It's such as great pose like the front double bocep pose...if you can't pull it off it becomes quickly evident and your weak parts really jump out, unlike the most muscular or palms in front of you together.
I wish I had the lats to do it.....
It also seems to me to be one of the best poses for all around muscularity. In some ways it might be the best pose for displaying a powerful physique...which is why I think it fits certain body styles like Yates, Reg or even Franco.
I think that Coleman drug usuage gave him a Herculean look but I dont think its his natural style. Look at his younger pics and his lines are more graceful. You can't say the same with Yates...he looks like a mug from the beginning.
