Dan Egan's latest book and free app All-Terrain Skiing II condense Egan's 40 years of ski experience into an approachable guide to help skiers of all abilities take their skills to the next level. The app features video demonstrations and step-by-step instructions for 31 exercises so skiers can master their body mechanics and balance, from powder to ice and all the conditions and terrain in between. Whether you're a beginner or a pro, these resources will help skiers master the skiing mind, find expression in the mountains, and build confidence. App users can purchase the book All Terrain Skiing II for more detail and description and then carry the AST app to the hill to practice. All-Terrain Skiing II is an integrated, self-contained program for beginning, intermediate, and advanced skiers-in other words, anyone who wants to learn to ski better. Lessons are identified with international trail marking symbols: Green Circle for beginners, Blue Square for intermediate, and Black Diamond for expert. In the ATS app, drills are also categorized to help you organize your lessons for quick access. These drills help you make body alignments while in motion, which ultimately increases your efficiency of motion and allows you to ski longer and with more control. The goal is to develop a new awareness of your relationship to gravity in a variety of ski conditions; to dynamically orient and angulate your body to maximize your control and efficiency; and to achieve constant fluid motion. The goal of this program is for skiers to become aware of every aspect of their body positioning in order to expand where and how they ski the mountain. The app will be available for mobile download on both iOS and Androids as All Terrain Skiing (ATS).
