A campus board (or pan Güllich) is a training tool that has been widely adopted by sport climbers to improve their plyometric performance and led to dramatic improvements in climbing technique in all rock climbing disciplines. The campus board was invented in 1988 by German climber Wolfgang Güllich to help him climb the world's hardest consensus-graded route at the time, Action Directe, and has since become a standard training tool for climbers.[1]
Other climbing training 'boards' have been developed since the campus board, including the MoonBoard, a small customized overhanging indoor climbing wall also for plyometric performance, and the hangboard (or also the fingerboard), a device for building up static strength, particularly in the fingers, but also in the arms.
