Aziz Sergeyevich Shavershian - many people know the story of Zyzz, and many have been motivated by it to live a healthier lifestyle. Zyzz was an Australian amateur bodybuilder born in 1989 - died in August 2011 by a heart attack in a Bangkok sauna (even though his brother Said "Chestbrah" Shavershian doesn't believe he died this way).
Zyzz started working out to become bigger. He did, and so did his name on the internet. Called "The god of aesthetics, son of Zeus, and brother of Hercules" by his followers, there's currently 250,000 fans on his facebook fanpage, up from 40,000 before his death. His legacy lives on and is only getting stronger.
A few facts I thought might be interesting:
-He covered his famous "Veni, vidi, vici" tattoo with roses in his last days in Thailand
-According to his brother, the Thailand authorities kept changing the cause of his death, even said he fell asleep on a massage table and didn't wake up. They also performed autopsy without permission before bringing him back to Australia
-He wrote a book of his personal knowledge and experience in bodybuilding
-He studied business and created his own supplement label "Protein of the Gods"
