Don’t you believe in “God Given Genetic” ..? Don’t you believe in “Always there is an exception for any base” ..?
So, based on your analysis that you are stating about Phil’s arms having SEO, I think you also think all of the following had SEO since they look crazy big and very detailed:-
Ronnie Coleman’s: Back, chest, legs.
Dorian Yates: Back, Calves
Tom Platz: Legs.
Pule Demayo: Legs
Kevin Levrone: Shoulders, Traps & Arms.
Roelly: Triceps
If using SEO would make my arms look like Phil’s arms, please tell me where to buy them! 
you are comparing few generations here,,you are confusing alot of things ,,its just too much to go into detail and try to explain it ,,ill put it in simple terms,,generation rolley and phil heath ...NOT bodybuilders! ,,roley is better but still this is generation that is based SOLETLY ON ABUSE OF HGH AND INSULINA,,
there is no god given genetics,,if there was then many of the 160lb 5'10 fellas would be mr o ....all the god given geneticsa baloie is excuse of fellas to go comepte ala naturalo when they are hormonized to the max,,,trust me friend i know what im talkin gabout they all come to my elfs to buy products,,and they buy it on a regular baiss month after month year after year for many many many years,,i keep saying it here,,they spend about 100 k in a period of 5-10 years on hormones,,you heard that right,,a nice private university tuition on the hormones needed to achieve the mission
between 40 and 100 k
now it is importnat to understand the diff between ron colman and some no one like heath ,,heath can not get shredded,,he has good muscle shape but he is done with being shredded ,,he is as soft as a baby butt,,he can be LOW BODY FAT....but havign a dorian and ron like condition or dex like condition from the past...forget about it,,same for the rest of the morons now day ,,but heath is prime example because he took all of the bad things from ken wheeler all the seo all the fake...he added it to gh and insulina aka luke wood ...... he did a mishko on a wheeler but with OUT the foundation
