He may be able to battle against most things that come his way, but now Rich Piana has been left fighting for his life after being placed into an induced coma.
The bodybuilding champion, who has over one-million followers on Instagram, suffered from a 'medical emergency at home'.
He fell ill from an undisclosed illness at his house in Florida yesterday, TMZ reports.
Piana, 46, has previously openly admitted to taking steroids to help boost his performance - and weighs in at around 310lbs (22st).

No official from Piana's team has made comment yet as concern surrounds the former Mr California.
TMZ reported: "Law enforcement sources tell us... emergency personnel responded to a possible overdose call at Piana's home on Monday afternoon.
"When they arrived, Piana was unresponsive and was transported to a nearby hospital where he was placed into a medically induced coma."
It's estimated, with thanks to social media, that Piana's wealth has rocketed in recent years to around £1.9m.

When Deadspin profiled him last year they claimed the giant-sized man ate nine meals per day and drank huge protein shakes.
They wrote of his lifestyle: "His world is one of excess. His homes are sprawling fortresses. His multiple cars are expensive and highly modified.
"His meals give a normal person sympathetic stomach aches just to look at. His workouts are gruelling and intensive.
"His steroid doses are so big that other bodybuilders make videos pleading with him to stop."
Despite repeated callings from many to stop taking steroids, Piana happily declares himself as 'the bodybuilder in the world'.
He started bulking at the age of 15, and has used steroid, on and off, for 27 years.
However, he did warn others not to take steroids, once saying: "If you have the choice to stay natural or do steroids, stay natural."
The website drugabuse.gov also adds that using anabolic steroids can have 'adverse side effects', including: acne, breast development in men, heart attacks and liver cancer.
"Most are reversible," it adds, "if the abuser stops taking the drugs, but some are permanent, such as voice deepening in females."
