Learn the correct pitching motion with the Plyo Training Ball. The Plyo Training Ball is designed for people who want to throw fast balls consistently, or who have repeated shoulder or elbow injuries! This is a training ball that will help you learn the correct pitching motion to reduce the risk of injury. Throwing with the whole body improves pitch speed. Throwing a heavy ball requires the use of the entire body, and by using the entire body to throw with awareness of the difference in rotation between the upper and lower body, you can expect to improve your pitching form and increase your pitching speed. Let's improve control with stable form. Once you acquire a sense of throwing with your whole body, you will be able to throw more stably, and you can expect to improve your control. This is recommended not only for pitchers, but also for outfielders who want to send the ball accurately. Hitting training is also possible. The Plyo Training Ball must be hit on the core with force at the moment of impact to fly well, so it can also be used for practice to improve impact and mitt power. To prevent injury, please start with a light ball and limit the number of hits.
