Every player wants to throw harder with more accuracy, while protecting their arm.  Now they can! 

Since 1996, the ARM STRONG has been strengthening and protecting the arms of baseball players. Many coaches and parents give credit to the ARM STRONG for the increased velocity and arm health of their players.  Dr. Phil Donley, an inductee to the N.A.T.A. (National Athletic Trainers Association) Hall of Fame says “the ARM STRONG is the best conditioning and reconditioning device for shoulders of throwers in the past 40 years.”
