David Meyer is an author, entrepreneur, and among the nation's leaders in rehabbing athletic injuries. I got to see the latter first hand when we crossed paths in the Cardinals organization. Since then, he's gone off on his own and founded Pipeline Performance with the mission to "guide those facing physical challenges to drive their thoughts, emotions, and physical state towards doing what they love, along with a more purposeful life." Whether you're trying to make the jump from AA ball to the Majors, or you're just trying to figure out how to play with a sprained ankle for your slow-pitch game on Tuesday, there's some value in here for everybody.
