Shoulder Rotator Cuff Injury Planking Ball Crosses
Place a ball underneath you between your hands. This will be the centre position for the ball as you will be moving it out to one of four positions each time and back to centre again.
Begin in a plank position and engage your lower core by trying to make yourself skinnier below your belly button at your waist line. Supporting yourself in a plank with your right side, move the ball from centre to up above, then back to centre, then from centre out to the left and then back to centre, and then from centre to below and then back to centre again.
Finally from centre out to the far right and back to centre again. Switch and plank on the left side now and move the ball with your right hand. Do 10 reps on each side daily.
You can utilize this exercise for rock climbing and many other different throwing sports such as baseball, volley ball or ultimate frisbee that require core stability and shoulder strength.
