We sat down with Said "Chestbrah" Shavershian, professional bodybuilder, online coach, and older brother of Zyzz, to talk about dragging his little brother off World of Warcraft and into the gym, the forum thread that named him, the birth of "aesthetics," how "we're all gonna make it" curdled into "I mog you to death," the hard drive of unreleased videos that made Zyzz more famous in death than in life, and what it means to carry a legacy for two.
