This video will teach you how to use the trunk to throw harder. The trunk is the final movement of the kinetic chain that drives the arm speed. If you have a poor trunk dynamic in your pitching delivery then you will use the arm to generate all of the forces on the ball. The small muscle groups in the arm may be able to generate a lot of ball speed but they will burnout or fatigue when used to generate power a lot faster than the big muscle groups in the trunk and legs.
Most low velocity pitchers have either a poor understanding of how the trunk moves in the high velocity delivery or have a break in the kinetic chain which is preventing the lower half power from moving the trunk dynamically. No matter the issue all low velocity pitchers will considerably benefit from learning how the trunk moves in the high velocity delivery.
In the video above you will learn the ranges that most high velocity pitchers use when it comes to the trunk dynamics of the pitch. You will need the 3X Pitching Velocity Program to help you train yourself to implement these trunk ranges.

The Key to Using the Trunk to Throw Harder

Here is a list of tips to help you implement more trunk dynamics.

  1. More hip to shoulder separation.
  2. More contralateral trunk tilt at front foot strike.
  3. More hip rotation into front foot strike.
  4. More front leg extension before pitch release.
  5. More linear front leg at foot strike.
  6. More shoulder abduction and external rotation.

The pitching mechanics listed here in these tips come from the 3X Pitching Mechanics Guides. To learn more about these pitching mechanicsĀ and how to implementĀ them checkout the 3X Pitching Velocity Program! The trunk of the high velocity pitcher is the most challenging movement to develop. You will need a program to help you have success in implementing it into your pitching delivery.
