I agree but what are those genetic limitations? How do you know you have gone as far as you are gonna go? Training isnt the only thing holding him back but the video I saw of him sure isnt helping him any.
Well, I know there are definitely cases where people are truly lazy and don't train properly, and then blame it on all drugs or genetics. I completely understand that. But, I'm willing to give dj the benefit of the doubt, he has a decent framework and is obviously obsessed with bodybuilding. I don't know how anyone would have the energy and persistence to type all this out day after day, week after week, if otherwise.
I don't know what one's true limitations are. Most who turn pro obtain pro card size within a few years, they "respond better than their peers" , ie exceptionally. I'm sure genetic science can already answer these questions within an accurate estimation.
