Kinetic Tube (J-Type) Official Ball Used

This is a training tool to help pitchers improve their form.

It helps prevent shoulder and elbow injuries in children and, more importantly, improves performance such as increasing ball speed!

It is effective for players who throw with an arm-like motion (where the elbow is fully extended), similar to batting center machines, and for players who tend to throw with their hands, where the elbow leads the body.

It's not just for pitchers; fielders also need to experience the correct way to use their bodies from a young age.

It's too late to wait until your shoulders and elbows hurt. And just because they don't complain of pain doesn't mean they're fine. Children who clearly throw with their hands have room for improvement and can throw better balls.

Detailed usage instructions will be included, but one thing we want to convey upfront is that this is not a strength training tool that pulls the ball (the photo showing the elbow bent and the arm in front of the body is an example of bad form).

If you use your hip joints effectively and initiate the rotation of your waist from your lower body, your chest will naturally expand, and because the tube is tied behind you, your elbow will naturally snap (lag) and follow. You can experience this kinetic chain of the entire body!

We hope you will take this opportunity to master an energy-efficient, efficient, and supple pitching form created by the kinetic chain!

If we can prevent even one player from suffering from baseball shoulder or elbow, that would be great...

Furthermore, we offer a small discount if you purchase the yellow tube for inner muscles or the spin-up roller, which helps increase ball spin rate, at the same time.

Honestly, children are more attracted to the spin-up roller, but this product is what we want the most for young baseball players to use.

We recommend this set of kinetic tube and spin-up roller!

 This product is designed to be attached to a high place, but leaving it hanging all year round will accelerate the deterioration of the tube.
 Ideally, it would be for personal use and practiced diligently indoors, but it might be a good idea for a team to purchase one and attach it to the backstop of the field only on Saturdays and Sundays, and have players use it during breaks or lunchtimes when they have free time.
 The color of the band used to attach the tube may change.

Thank you for your understanding.
