Get products specifically built and designed for baseball pitchers

We’ve created products and protocols that are designed specifically for baseball pitchers. While nothing can replace our in-person group and individual workouts, our products will help you increase velocity, build strength, and increase arm durability while helping you avoid injury.

The NPA has been researching and improving pitcher performance for over 25 years! You can be confident that all of our offerings have been researched, tested and refined to help pitchers make gains safely. We take pride in what we do and it’s why we’re the most trusted source for pitching-related info anywhere!.

Velocity Bat Set

These weighted bats help develop optimal hip and shoulder separation and increase shoulder rotational speed. Both are crucial to helping INCREASE THROWING VELOCITY without adding stress to the arm. For position players, these bats also INCREASE BAT SPEED and exit velocity dramatically! For more detailed information visit our partner site Add the bats to your workout program and within weeks you will be throwing harder and increasing your bat speed!


Our Youth Starter Program is an arm and shoulder durability routine to keep kids healthy while they mature through little league and travel ball. We use weighted balls in a very safe and tested manner that helps prevent kids from getting sore arms or worse. Unlike the standard weighted ball programs where kids are throwing weighted balls inappropriately, our program takes into consideration the developmental stage that youths are in and focuses on arm durability that will manifest itself into a stronger arm and more velocity as they mature physically.


This is what started it all! The current overload/underload phenomenon to increase velocity started with this program originally developed at the NPA (National Pitching Association).


This is the digital download of the PDF manual of the most comprehensive velocity, shoulder care and joint integrity program that you can get without working with us at our facility. This is NOT A COOKIE CUTTER PROGRAM. This workout adapts to you as you increase your velocity and/or innings totals.
