Ronnie has the bloofy/watery look in pretty much every picture i have ever seen of him, he has genetically more detail in certain muscle groups than Yates, deeper lines, more striations, that is not conditioning. Yates was far drier and denser looking.
Drier? I think Yates looks far more watery than Coleman 90% of the time, Ill let the pics talk for themselves.
Denser? That is not even a real thing, protein muscle fibers are protein muscle fibers, who has more who has less is a weight thing. Even then, I do not think this true, Coleman looks like muscle with skin, he is as dense as it can look.
Certain muscle groups?
