The world's largest biceps belong to Mostafa Ismail (Egypt) and were measured for left arm flexed at 64.77 cm (25.5 in) and non-flexed 62.23 cm (24.5 in) and for right arm flexed at 63.5 cm (25 in) and non-flexed 60.96 cm (24 in). The measurements were taken in Franklin, Massachusetts, USA which is where Mostafa now resides.
Moustafa Ismail of Massachusetts says having arms as wide as an adult man's waist comes with plenty of unexpected challenges, including difficulty in finding shirts whose sleeves would fit his 31-inch muscles without dwarfing his 5ft 11 frame.
Moustafa Ismail's eye-popping biceps and triceps are a result of a punishing workout regime that began after a guest at his uncle's wedding mocked his overweight frame in his native Egypt.

More than a decade later, the 24-year-old bodybuilder says he was surprised by recognition in the 2013 edition of the Guinness World Records as owner of the largest upper-arm muscles on earth.
"They call me Popeye, the Egyptian Popeye," an amused Ismail said of the media reaction after the announcement in September. But unlike the cartoon character, he says he "hates spinach and loves chicken".
Poultry, seafood and shakes provide nearly seven pounds of protein he needs every day to nourish the massive muscles, Ismail said while working out at the gym in the Boston suburb of Milford.
About nine pounds of carbohydrates, at least three gallons of water as well as various mineral and vitamin supplements account for the remaining sources of sustenance, he says.
Ismail quietly begun building his muscles in his Egyptian hometown of Alexandria before moving to the United States in 2007 and settling in the Massachusetts town of Franklin, located about 27 miles southwest of Boston.
Keen to pay for his gym membership and hefty dietary requirements, he worked two jobs as a gas station attendant for several years. He gave up one job after his Colombian wife complained that he was pushing himself too hard.
And then Guinness World Records came calling, offering him an all-expenses-paid trip to London for a signature appearance with the world's shortest woman and other anomalies highlighting the latest edition of world records.
Ismail said he was stunned by a barrage of allegations from strangers who claimed that he either used steroids or had implants in his arms. Others speculated that he might have injected his muscles with a synthetic oil substance known as synthol that is used by bodybuilders to artificially fluff muscular tissues.
