{{ cr.title }}

Every pitcher has one thing holding him back the most. Fix it, and he unlocks a whole new level of performance. We call it his primary constraint. We assess each athlete, identify that constraint, and spend about 80% of his training time on it. We also find secondary constraints we can work on in parallel without taking away from the primary one. Many of the tools we use for the primary constraint help with the secondary ones too.
