George Caddy :: This image brings a smile to most people familiar with Max Dupain’s iconic Sunbaker 1937. In fact, it is an exercise designed to strengthen the chest. As Health and Physical Culture (1 May 1935) noted: ’… the breath is literally trod out of the figure on the floor. The idea is to make the chest as elastic as possible – hence full inhalation followed by treading and then complete relaxation and inertion.’ 20 February 1937.
