for the most of it, it is purely genetic, referencing the picture.
i have 1 friend i workout with a lot and he has the triangle v-taper shape, but he doesn't go for aesthetics, he eats whatever and just lifts enough to maintain, not gain. He's more of a fighter than a lifter, trains hard in boxing and can jump rope like a madman, but he didn't suffer a diet plan and exhaust himself at the gym to earn his body, he was mainly born with it.1
