Spine Extension and Flexion is an extremely important movement when throwing a fastpitch pitch. As with all movements, there are efficient and inefficient ranges of motion. Rick will discuss and show both. In addition, he will explain what happens when a pitcher is outside of an efficient range of movement and how to correct this. As always, there is a health/injury factor to be understood. Again, Rick will point out the risks when a pitcher is outside an efficient range of motion. A couple of my favorite Pitching Instructors, Shaun Walker and James Clark, will add some valuable insights into this presentation.
