This man is probably one you wouldn't want to mess with - he holds the title of having the biggest biceps in Russia.
Ukraine-born Denis Cyplenkov is a member of the Russian strongman team and the winner of multiple arm-wrestling championships. He said "arm wrestling has always lived in me, but at the amateur level."
In 2008, he began his path to becoming a professional arm wrestler when he was given the opportunity to train under armsport hero and coach, Kote Razmadze.
"I gladly agreed. Under his leadership, I became the owner of Intercontinental belt and won the world title among professionals," he said.
The strongman is reportedly over six feet tall and weighs 140kg.
He has a bicep circumference of 2 feet (63cm), an upper arm circumference of 1 feet 6 inches (46 cm) and a wrist circumference of 9 inches (24 cm).
As seen in pictures, his biceps are easily three times the size of a normal man's arm and the pinkie of his hand is bigger than the thumbs of most people.
