Son Hyuk: Son Hyuk's Pitching Textbook

The secret of the Major Lisars to throwing 150 km/h by the age of forty is the bowling textbook of Gwanson Hyuk. A manual of the system-synthetic Messeriger helmet form. He came to America and he wanted to convey as easily as possible what he felt and felt. The Easterners are very confident that the body is not enough to make a physical difference, because of the preconceived notion that the Western helmet action cannot be applied, and they want to pass on the secret of throwing a fast ball without injury. A study of hundreds of helmet forms, such as the most advanced bowlers in Major League, ran out of nine helmet movements, and then produced a common denominator, using eight different helmet movements that are misleading in the world of Korean baseball, to illustrate the principle of the helmets that may actually be being taught by the Major League. It helps them to follow the first baseball players and the professional players who desperately want to correct their helmet form.
