The Cafe Kraft gym in Nurnberg, Germany has gained a great reputation for coaching a string of fantastic climbing talents over the past few years, most notably, Alex Megos who became the first climber to onsight 9a. Their coaches have put together a book and DVD detailing the principles and exercises they have used to help their talented young climbers become super strong and fit beasts.
The book is very focused on physical strength and endurance training, both on and off the climbing wall. It provides a great and easy to follow manual for sharpening up weak areas in your strength. This is particularly useful since it can be hard to choose or adapt core strength routines from other sports for climbing.
Both the book and DVD show clearly how to do the basic strength and endurance exercises and the DVD contains many interesting interviews with climbing legends about training and climbing performance.
