The document discusses resistance band stretching and its benefits for increasing flexibility for baseball. It defines flexibility and different types, explaining how resistance band stretching mimics functional movement by using momentum, gravity and active stabilization. Static stretching is not optimal for baseball as it can inhibit the central nervous system, while dynamic band stretching maximizes muscle length in a controlled manner similar to on-field movements. Guidelines are provided for an effective band stretching routine targeting the ankles, hips, shoulders and full kinetic chain for improved flexibility and athletic performance in baseball.
