As seen on NBC's American Ninja Warrior Cannonball Alley, the XXL Cannon Ball is an advanced level pull up ball meant to build forearm and upper body strength. Its large, spherical shape forces the hand into an open grip position, targeting forearm muscles specifically. Our 9" Cannon Ball is a versatile pull-up training tool and can be used in a variety of different style workouts.
