If you spent the last decade pumping iron twice a day, you too can develop these absurd-looking biceps belonging to Egyptian-born bodybuilder Moustafa Ismail or 'Big Mo'. Trust us when we say this is one guy you don't want to arm-wrestle with.



The 24-year-old has just been titled as the man with the largest biceps in the world which measure in at 31 inches (about the same size as your average guy's waist!). All we can say  is that sitting on those guns definitely does not look comfortable.



According to Daily Mail, the bodybuilder was apparently so dedicated to bulking up his arms that he relocated his whole family to America because they have access to better workout equipment. 'Big Mo' needs to eat at least 3lbs of chicken, 1lbs of steak or fish and four cups of almonds washed down with two gallons of water and three litres of protein shakes to maintain his physique.
