In all martial disciplines—including karate, judo, taekwondo, and gong-fu—real martial skill does not require the development of large muscles or great strength but rather correct posture. Drawing on decades of experience as both a student and a teacher, Phillip Starr focuses on how physical posture affects not only physical abilities but also the mental condition and emphasizes the importance of developing power without exerting unnecessary muscular force. Thoroughly and accessibly explained and abundantly illustrated throughout with photographs that provide step-by-step instructions, is essential for anyone wanting to understand how the laws of physics and biomechanics can be harnessed to make them faster, more powerful, and more effective in actual combat.
