<p>A device for learning pitching technique for ball games and improving muscle strength through resistance training. The device (1), which consists of an elongated U-shaped coiled tubular spring with a curved end and a pair of straight parallel shaft portions (34A and 34B) with solid tips (16A and 16B), is aligned with and strapped to the user's pitching forearm (22). The device adjusts to fit the forearm. A rod or elastic string (6) is fitted through a sleeve (3) in the ball's (2) internal polar tunnel, and the opposing ends of the rod or string are attached to the tips so that the ball can be spun around the rod or bounced on the string, to simulate pitching. A shock absorbent casing (36) on the curved end and strap (6) increases comfort. Opposing ends of an elastic band can be attached to the device and a stable object, such as a pole, to perform resistance training.</p> |
