3. LATERAL RAISE: Grasp the handle of the Power Grip-Ball™ Shell with the palm facing
towards the midline of the body. Standing erect, slowly raise the arm directly away from you.
Keep the palm on the hand facing downward. The elbow should always be level with or above
the Power Grip-Ball™ Shell to reduce the risk of injuring the shoulder girdle. When the arm is
parallel with the ground, pause briefly and then slowly return the arm to its starting position.
Repeat as desired.
4. UPRIGHT ROW: Start with the Power Grip-Ball™ Shell held between the thighs. Feet should
be shoulder width apart, knees bent. The waist should be bent just enough to keep the torso in an
erect position. To complete the exercise attempt to raise the Power Grip-Ball™ Shell directly
upwards towards the shoulders, bending the arm at the elbow. Keep the ball close to the body
throughout the lift, while keeping the elbow out to the side of the body. At the top of the lift the
ball should be just below the shoulders. Pause briefly and then return slowly to the starting
position. Repeat with the other arm.
5. INTERNAL/EXTERNAL ROTATION: Start with the Power Grip-Ball™ Shell securely held
in the hand of the arm to be exercised. Flex the elbow to 90 degrees while keeping it in contact
with the body. The Power Grip-Ball™ Shell should be extended out in front of the body, with the
forearm parallel to the ground. Slowly rotate your arm at the shoulder, moving the ball in
towards the abdomen. Pause upon contact with the abdomen and reverse the rotation until the
ball is extended outwards from the side of the body. The amount of external rotation will vary by
individual. DO NOT attempt to force rotation at the shoulder, as this could result in injury.
6. POWER SIDE THROWS: Start with Power Grip-Ball™ Shell securely held at arms length
away from the body. Using the legs and torso twist as if trying to reach behind the back. When
you cannot reach any further, quickly rotate in the opposite direction, acceleration the Power
Grip-Ball™ Shell. Release the Power Grip-Ball™ Shell as the ball passes in front of the body.
Allow the arm to follow through past the opposite leg to naturally decelerate the body. Repeat as
desired. NOTE: Due to the intense effort of this exercise, the user is advised to wait
approximately 3 minutes between throws. Repeat with other arm.
Another variation is to reverse the rotation of the body, starting with the ball in front of the
opposite leg and then rotate across the front of the body releasing the ball as the arm extends
laterally from the body.
7. OVERHEAD THROWS: Start with the Power Grip-Ball™ Shell positioned in front of the
body, between the legs. Initiate the exercise by squatting down, as if to perform a vertical jump.
Forcefully extend at the ankles, knees and hips while keeping the shoulders back and torso erect.
As the legs reach full extension quickly accelerate the ball upwards using the shoulder, arm and
back muscles. As the arm extends overhead, release the Power Grip-Ball™ Shell and step
forward. Follow the flight of the ball to prevent the ball for landing on the user.
