This groundbreaking series uses the latest MRI scanning technology and cutting edge CGI modelling to look deep into the structures of some of the most amazing human bodies on the planet. Extreme Bodies reveals the remarkable skeletons and physiological systems of people who live life far from the average. We meet America's heaviest athlete, a family of giants, a dwarf track & field Olympian and the extraordinary twin girls who not only share a physical connection but who may also think and feel together. This is a journey to the outer limits of the human body's potential and into the extraordinary lives of some the world's most unique people.
