Arnold Schwarzenegger – a bodybuilder-turned-real-estate mogul who turned an undefeated streak at the Mr Olympia contest into an astonishing film career and eight years as the governor of California – is, for many people, the embodiment of the American Dream. From humble beginnings in a small village in Austria, Schwarzenegger has come to symbolise the opportunities that exist for anyone willing to work hard – parlaying success and self-confidence into the influence to shape hearts and minds across the globe. Even today, whether he's campaigning against climate change or fist-bumping fellow strongmen at his self-titled athletic event, he's one of the few men on the planet who's recognisable from his first name alone. Arnold.

Fiaz Rafiq uses in-depth interviews with Schwarzenegger's peers to tell the life story of the one-time Governator, featuring exclusive interviews with his personal and close friends, fellow bodybuilders and training partners, Hollywood co-stars, directors, executive producers, political personalities and journalists – all offering first-hand accounts of the man they know. Together, these voices show new dimensions to the Arnold we all think we know – from the driven young man who brought building into the mainstream to the passionate advocate for political change.
