Overhung board with thin (one joint or so) wooden holds; meant to be ascended without using the feet. Can destroy tendons astonishingly fast. The acme of achievement is "1-5-9" (double-handed dynos from the first to fifth to ninth hold).

The campus board is a rock climbing training tool, usually made from thin slats of wood attached to a board in a ladderlike fashion, then hung at a less than vertical angle (around 20 degrees) somewhere with plenty of leg room. Climbers ascend and descend the board using only their hands, alternating the use of fingers to develop finger and upper-body strength. The implement was invented by Wolfgang Güllich in 1988 to help him train for a new route, Action Directe, which required extreme dynamic finger strength.
