just with the challenge of a real route. Although Güllich enjoyed traveling to other locations and testing himself on their hardest routes, saying: "A 'successful' climber is someone who has done many hard routes in many areas, not just a local specialist", he was most motivated by creating new routes, saying: "if climbing is an art, then creativity is its main component". Güllich maintained an intensive and scientific approach to training for climbing, sometimes taking on specific training techniques for individual climbs. While training for Action Directe, Güllich invented the campus boarding to develop plyometric strength in his fingers and arms. Güllich co-authored with Andreas Kubin a 192-page German book on training for sport climbing called Sportklettern heute (1986), and was an early advocate of bouldering as a way to improve his technique and build performance, saying "the hardest routes are extended boulder problems"; he also studied the use of the "deadpoint". Güllich's advice would often extend beyond the physical, and was a source of notable quotes indcluding: "A man doesn't go to drink coffee after climbing, coffee is integral part of the climbing". Legacy Güllich is considered one of the greatest and most influential climbers in the history of the sport, and a pioneer in both technique and training. In 2013, when National Geographic announced Adam Ondra as an "Adventurer of the Year", they noted that the title of "world's strongest climber" was held by Güllich in the 1980s and early 1990s, then passed to Chris Sharma in 2001, and to Ondra in 2013; National Geographic said of Güllich: "In the '80s and early '90s German climber Wolfgang Güllich almost singlehandedly bumped the highest grade in rock climbing from 5.13d to 5.14d". In 2018, when Beth Wald wrote a preface to her 1987 Climbing interview with Güllich for the book Vantage Point: 50 Years of the Best Climbing Stories Ever Told, she introduced him as: "One of the finest rock climbers of all time the German Wolfgang Güllich developed cutting-edge training regimes that today have become commonplace...". In 2022, on the 30th anniversary of his death, PlanetMountain called him: "A truly visionary figure, his influence extends well beyond sport climbing and even today his routes in far-flung corners of the globe such as Patagonia and the Karakorum are considered absolute milestones in big wall climbing in the high mountains". In 2022, Die Zeit called Güllich, "One of the best
