Swing your arm, led by your pelvis (arcuate line), and if the sound "Phew" is made at the same time as you release the ball, your arm swing is correct. ---------------------------- 【Throwing Partner】 Features: Learn how to throw in a way that reduces shoulder and elbow injuries! This solves the problems of "the arm moving away from the body" and "the elbow dropping." Recommended for baseball beginners and players who want to correct their throwing form. ● Ball Diameter: Approximately 18cm ● Material: Vinyl chloride resin ● Weight: Approximately 10g **The included air pump is missing. Since the ball does not have a check valve, it could be used without an air pump. ---------------------------- 【Throwing Master】 ◇ Master the ideal wrist snap during pitching! ◇ This is a novel ball that allows you to learn the movements from the wrist forward, especially the effective use of the snap, which is essential during pitching, just by throwing it. It features a non-slip surface, a moderate weight to make you aware of the upward movement of the wrist, which is essential before throwing the ball, and a calculated size that requires a wrist snap when throwing. ■ Material: Rubber ■ Usage: Pitching practice ■ Size: 12cm in diameter ■ Weight: 150g ■ Country of Origin: China * There are no instructions or boxes.
