Building strength in the stride leg of a pitcher is essential for developing a stable balanced support as the arm and body aggressively enter the acceleration and deceleration phases of throwing.  The arm reaches its highest velocity and greatest range of motion during these two phases, so it’s critical for the pitcher to land on a solid, stable base.  This is a task specific a drill that can be added to a traditional strength training routine for building stride leg strength while rotating and weight shifting  from back to front and right to left.
