When theyre not flexing their carefully sculpted triceps, biceps and glutes, how do world-class bodybuilders spend their time at competitions?

In 2014, Daniel Gebhart de Koekkoek , a photographer interested in dedicated, insular communities, went to the World Bodybuilding and Physique Sports Championships in Vienna, Austria, to find out.

His previous project, The World We Live In, was all about small worlds and microcosms. Worlds people build for their own while they put a lot of passion and effort into what they are doing and forget about everything else, Gebhart de Koekkoek told The Huffington Post in an email. So, it occurred to him to photograph bodybuilders, who he said live in their own small world.
