Finally understand where real golf power comes from - and how to build it safely.Golf Biomechanics - The Power Train strips away swing myths and replaces them with clear, science-based principles that explain how efficient golfers generate speed without pain, strain, or breakdown.This book is not about copying positions. It is about understanding how the body produces force, how energy transfers through the kinetic chain, and why efficient motion always outperforms effort-based swinging.Using biomechanics, physics, and real-world coaching insight, this volume explains: - How ground reaction forces initiate the golf swing - How the pelvis, torso, and arms sequence to create efficient speed - Why excessive arm effort reduces power and control - How rotational force replaces stress-based swinging - How to build speed while protecting the spine, shoulders, and wristsDesigned for longevity and repeatability, this book provides a clear framework for building a durable, injury-free golf swing from the ground up. Readers learn why great ball-striking happens, not just how to imitate it.This is Phase 1 of a progressive system focused on efficient mechanics, measurable improvement, and long-term physical health. Ideal for golfers, instructors, trainers, and movement professionals who want to understand the science behind consistent performance.
