Mark Hunt has seriously heavy hands. Ask Antonio Silva. Or Roy Nelson. Or any of the 21 fighters the kickboxing and mixed martial arts star has knocked out during his career.
So freely offering to take a shot from the man known as the "Super Samoan" doesn't seem like the smartest idea.
But that's exactly what this youngster from Queensland, Emiliano "Noodles" Rivera, put his hand up for during a recent training session.
By the looks of his Instagram page, "Noodles" deserves serious congratulations for the way he's transformed his body lately - but he still has a reasonable layer of protection around his midsection.
That doesn't mean this video is any less impressive though. Hunt might be swinging with his less-dominant left hand, but he appears to put everything into the blow.
If you're still sceptical, read the reaction of long-time UFC commentator Joe Rogan, who shared the video on his Facebook page.
"That is insane. The stuff of nightmares," Rogan wrote. "Nothing scarier than a guy that can laugh off a full power Mark Hunt body shot."
"Noodles" is the nephew of veteran Australian fighter John Wayne Parr. He knocked out his first opponent in six seconds when, according to Parr, he weighed 125kg and had only been training for 10 weeks.
With that type of one-punch power - not to mention his obvious ability to take a shot - perhaps we'll see "Noodles" competing near the level his famous uncle reached.
