Core Insights & Research

Unveils overlooked aspects of biomechanics and delves into Spinal Engine Theory, explaining the spine's pivotal role in movement and its application in pitching mechanics.

Pitching Mechanics Deconstructed

Provides a detailed, phase-by-phase breakdown of the pitching delivery, informed by Spinal Engine Theory, and identifies the key components necessary for an efficient 'spinal engine.'

Practical Application & Tools

Offers a comprehensive training program with over 25 tailored exercises and utilizes more than 30 visual aids, including GIFs, to translate theoretical insights into actionable coaching and performance enhancement strategies.

"The spinal engine e-book does a fantastic job of tying together theory and application. I'm confident coaches and players across all levels of our sport will benefit tremendously from this seminal piece. I strongly recommend this resource to anyone eager to understand the pitching delivery at a high level."

"It has been impressive to see the time and effort spent putting this resource together. If you're a thrower with a spine that moves like a 2x4 or someone who wants to reshape your understanding of the pitching delivery and gain a fresh perspective with a way to actually implement it, buy this book."

The Spinal Engine: Understanding the Pitching Delivery is the first available resource that unpacks the pitching delivery through the lens of Spinal Engine Theory.

Coined by Russian scientist Serge Gracovestsky, Spinal Engine Theory offers an alternative explanation for the role of the spine/core during locomotion. Rather than being a passive transmitter of energy as conventionally thought, the spine actually plays an active role in generating the torque that allows us to move our bodies.

So what does a theory about locomotion have to do with pitching mechanics? It turns out that locomotive activities such as walking and running share a major component with throwing a baseball: axial torque between the pelvis and thorax… or in common baseball language, “hip-to-shoulder separation.”

Hip-to-shoulder separation is one of the most commonly discussed terms you’ll hear regarding rotational sports (baseball, golf, T&F). It’s also one of the hardest phenomena to understand in terms of how it actually happens. For starters, the back leg does not rotate the pelvis! The axial torque between the pelvis and thorax observed in movements like walking, running, throwing, and swinging is not a byproduct of the back leg internally rotating. Hip-to-shoulder separation is instead driven from above by the spine!

If you're someone who has wanted to unlock the intended benefits of hip to shoulder separation and want to know how to cut through the misconceptions and actually make that happen, this book is for you.
