Bassendean-born Rik Kamana has come a long way in the two years he's been an arm-wrestler.
He is in Brazil this week for the world championships with the same can-do attitude that led him to kick drugs, lose 51kg and overcome a series of personal tragedies including a serious motorbike crash.
And when he has finished locking hands with some of the toughest guys in the world, he'll focus on his next dream - to climb Mt Everest and raise money for Telethon.
"I enjoy it and will not stop until I become one of the best arm wrestlers on the planet," he said.
Kamana, 37, has achieved plenty of personal goals in recent years, having made it his prime objective to turn his life around and be a better dad to his young daughter.
Rick Parish, founder of the Telethon Adventurers, is among those who have inspired him to look past material wealth for satisfaction.
Kamana climbed two mountains in Europe with the Adventurers, and has since become a volunteer at Princess Margaret Hospital.
He wants to highlight the fight against childhood spinal and brain cancers by scaling the world's highest peak.
"I felt like I needed to do more," he said.
