The foundation of the All-Terrain Skiing Guide is built on three concepts: 1. The Four Golden Rules of Change - Skiers need to adapt to change in Terrain, Conditions, Speed, and Situations. 2. The five All-Terrain Elements: Balance, Upper Body, Power, Fluidity, and Agility. 3. Practice right on the Slopes with the 19 weather proof "Chairlift Cards" to make your learning experience easier. Dan Egan's All-Terrain Skiing multimedia learning package for the beginning, intermediate and advance skier consists of three learning tools: this book with the pocket set of weatherproof instructional cards plus an instructional videotape.
