I had been climbing for about a year and a half when I stumbled across this book. People in the gym and at the crag commented on how all of a sudden I started progressing with my climbing more and more. This is a must have for climbers (and other athletes for that matter) looking to improve their all around climbing. I'm not the strongest reader in the world but this book got me hooked. Each week I look at new chapters, find new pieces of info on how to improve on what I'm doing; it's put everything into perspective. If your new or a veteran climber, I would strongly recommend this book. I try to sell this book when I'm at the gym. I'll even talk to people about tips for training, injury prevention, mental, and nutrition and they'll respond with "was that from the Horst book?" Absolutely. I'd give this book 4 star on mountain project, a classic carriage road test-piece! Thank you so much Eric!
