|This is my exercise ball version of the ball plank with feet on the
ball. Instead of
having the unstable surface under my forearms or hands I've put it under
my feet. Like the
plank on the floor, and the static plank with arms on the ball, this
plank on the ball works the abdominal muscles strongly as well as the
short back stabilizing muscles.
Because your back is horizontal there is a great force acting on your trunk to pull it down. This makes it more difficult than other planks. Also, a shoulder angle of 90 degrees makes this exercise more difficult than the floor plank where the arm is closer to the body.
