Mastering a True Palm-Up

Improve striking power by engaging your core and adductor muscles.

In batting, the "power to drive through the ball" is crucial. If you are overpowered by the ball at the moment of impact, the probability of hitting a weak fly ball or ground out increases dramatically. Many batters turn their wrists at the moment of impact, preventing power from being transferred to the ball. So, how do you overpower the ball? The answer is **palm up**. When you push the bat with your palm up, your driving power naturally increases, allowing you to hit the ball with more force. Using TRUNK BALL prevents your wrist from turning over, naturally teaching you to keep your palm up. Use 120% of your body's strength to improve your batting power = the power to drive through the ball.

FEATURE

特徴

  • Palm-up for a stronger push-in

  • Master a core-driven swing

  • Train your adductor muscles to increase explosive power

  • FEATURE 01

    Palm up increases pushing force.

    If you let your wrist turn over, the force is dispersed and your "pushing power becomes weak." Conversely, if you master palm-up, the force is not dispersed and your "pushing power becomes strong," allowing you to hit powerful balls. TRUNK BALL allows you to naturally master a palm-up swing without turning over your wrist.

  • FEATURE 02

    Master a core-driven swing

    A palm-up swing, which avoids twisting the wrist, prevents power dispersion and allows you to transfer 120% of your power to the ball. Using TRUNK BALL helps you master the palm-up swing, enabling a powerful swing that utilizes your core.

  • FEATURE 03

    Strengthen adductors to increase explosive power

    The strength of your adductor muscles (inner thigh muscles) changes your hitting power. The action and sensation of strongly squeezing your legs are important for making your swing stronger and faster. Using the TRUNK BALL allows you to efficiently train your adductor muscles, enabling a powerful swing.

  • Can be used by children and adults alike!

  • Inflatable for the lightest weight
