Extreme Bodies is an incredible series that looks deep into the structures of the most amazing human bodies Nature has ever created! Using the latest MRI scanning technology, combined with state-of-the-art CGI, Extreme Bodies reveals the remarkable skeletons, brains and cardio-vascular systems of people who live life far from the average. We meet America's Heaviest Athlete, America's Tallest Man, our shortest Special Track and Field Olympian and the Twin Girls who not only share a physical connection but who 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.
