Conditioning For Climbers by Eric Horst  helps climbers of all abilities to develop an achievable personalised physical training program. It walks clearly through  the importance of accurate self assessment, of goal setting and of specificity. The bulk of the book is filled with well illustrated exercises, both on and off the wall, to help maintain and build the important physical attributes for modern rock climbing. Helpfully, Horst emphasises the need for balanced development to maintain well being. The book closes with a brief look at nutrition and recovery.
