Campus board
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.
