Jack Knife

The Jack Knife exercise with the Swiss Ball works the lower abdominal muscles while engaging the stabilizing and core muscles.

Start face down with the shins on the ball. Lift the buttocks towards the ceiling until the knees touch the chest.

• About the Swiss Ball

  After suffering a back injury, I was recommended the Swiss ball to assist with rehabilitation. For my reference (and yours), this site lists exercises using the Swiss ball.
