Multi-Stage Fitness Test explores sex in pornography as both theatre and a physical capability. Sixteen ‘straight’ 1980s pornographic videos are arranged in grid and played synchronously to the audio directions of the Multi-Stage Fitness Test (the ‘Beep Test’). The sexual performances become increasingly absurd as their speed increases. Marked by the male orgasm ‘sexual fitness’ is determined whenever a video in the grid ends. The fitness test harkens to physical education in middle school reverberating periods of sexual realization in adolescents. Within this period pornography plays a heavy role in permeating heteronormative and stereotyped ideas regarding sexual behaviour.
