From a kneeling position place your forearms on an exercise ball, as shown in the first image. Draw your shoulder blades together, squeeze your buttocks and your local core and push up onto your feet. Your shoulders should be directly above your elbows, concentrate on keeping your balance and move from your forearms onto your hands. Your shoulders should be above your hands. Your body should form a straight line from your head down to your feet.
Concentrate on keeping your balance and lower your chest towards the ball, straighten the arms back out to return the the original plank position. Repeat for the number of repetitions indicated by your clinician.
Relax back down onto your knees. This completes one set.
Draw your belly button into your spine to activate your local core and support your lower back. Place your tongue on the roof of you mouth and relax your jaw to support your neck.
