When did society become obsessed with fitness? And are fit people really more successful? In his new book, The Age of Fitness, Professor of North American History Jürgen Martschukat traces the beginnings of our modern obsession with fitness - which arose in the 1970s amid the neoliberal era - and looks at how our physical health is increasingly linked to success, recognition and power. Professor Martschukat joins the show to discuss the almost post-religious reverence of fitness in an increasingly secular society.
