Power Throw-Ball™ Exercises
The Power Throw-Ball™ is a durable baseball- or softball-size ball available in 7, 14, and 21 oz.
The Power Throw-Ball™ helps develop dynamic strength through the throwing or rotation
motion. The soft core of the Power Throw-Ball™ allows for easy gripping during movements.
Below are a few exercises for the Power Throw-Ball™. Perform the appropriate number of
repetitions for your workout routine.
SHOULDER CUFF ROTATION
Starting Phase: Stand with the feet a little more than shoulder-width
apart, and bend the knees slightly. Hold the Power Throw-Ball™ in
one hand, and lift the arm until the elbow makes a 90-degree angle.
Place the opposite hand on the waist, and keep the torso erect.
Action Phase: Holding the Power Throw-Ball™ in one hand, rotate
the shoulder in a forward motion. Keep the elbow stable, and rotate
the shoulder forward as much as possible while maintaining this same
form. When performing this rotation, you should feel the movement
in the shoulder cuff; do not let the elbow drop as the muscles get
fatigued.
UNDERHAND ROTATION
Starting Phase: Stand with the feet together. Hold the Power
Throw-Ball™ with one hand in an underhand grip. Extend the
arm down by the side, but do not lock the elbow.
Action Phase: While grasping the Power Throw-Ball™ with
an underhand grip, begin to take a step forward with the leg
opposite to the throwing arm. As you are stepping forward,
begin to bring the arm forward and up in a circular motion.
When the ball reaches near the hip region, release the ball.
