Big arms, big fail: Russian 'Bazooka Arms' falls flat on his MMA debut (VIDEO)
Tereshin made his name by pumping his arms with synthol to increase their size to a freakish size. And his one-foot-wide biceps proved to be his Achilles heel as he was taken down and finished with an armlock that left the big-armed Russian in unbearable pain as he tapped out his submission.
Tereshin, whose Instagram account boasts 444,000 followers, is something of a cult figure on social media, with his decision to step into the cage keenly followed by his fans online.Also on rt.com Clash of the titans! Russian slap champ 'The Dumpling' takes on foot-long bicep guy 'Bazooka Arms'
Unfortunately, Tereshin, who admitted pre-fight that he was "not a fighter", found himself unable to cope with having one of his huge arms trapped on the mat.
