GUINNESS World Records has launched the latest edition of its best-selling book documenting global achievement, including new entries for the largest guns, the oldest gymnast and the lowest ever car.

Egyptian-born Moustafa Ismail, recognised for having the largest “guns” - biceps and triceps - with a circumference of 25.5in; and London-based sumo wrestler Sharran Alexander, who weighs 203.21 kg (32 stone), who was named the world’s heaviest sportswoman.

Bodybuilder Mr Ismail, now living in Franklin, Massachusetts, has arms with a greater circumference than the average human head.

The 24-year-old, originally from Alexandria, Egypt, hopes his record-breaking status will be a springboard to become a professional body-builder.
