canvasing, campasing, and, then, campusing

is the third time a charmer? i can't help but laugh (again). at first i thought it was canvasing, then campasing. but alas, it's campusing.

"'campusing'", or using just your arms and upper body to climb, originated in training guru, wolfgang gullich's campus gym in which he built many variations of the now known campus board. he formed the campusing idea to train his fingers and arms for the power required for his project, action directe. the contact (finger) strength and power that he gained from training on his campus boards helped him greatly in acheiving his goal, which is one of the hardest, most known climbs still today (5.14b) and is very seldom repeated.

although the word campus, in climbing, originated from wolfgang's training devices, it has also become the name for which we call any type of climbing in which no feet are used." -- excerpt from pawnclimbing.com
