The core is a key body segment for improving baseball performance and staying injury free. The core consists of the hip abdomen and back. The core is more than just the “abs”.  It is the relay center of the body that transfers force from the lower body (hips and legs) to the upper body (shoulders and arms) so that it can be applied to the bat and ball. The most important movements of the core in baseball are those that produce rotation. The majority of the core exercises in the Rangers’ program are performed in standing and moving positions because those positions functionally transfer to positions where the game is played. Some component of core training will be emphasized in every training session.
