Kirill ‘Bazooka Arms’ Tereshin may have arms the size of a normal man’s thighs, but his artificially-enhanced guns fired blanks on fight night as he was submitted by Russian blogger Oleg Mongol in their MMA fight.

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.
