Stability Ball Plank

Muscles Targeted: Abdominals

Place your elbows on a stability ball so that your elbows are directly underneath your armpits. Hold your body in a straight line from head to toe, keeping your legs straight. Hold for a given time period, usually starting with 30 seconds, working up in time.

To make the exercise more difficult, slowly roll the ball forward and back by moving your elbows while maintaining a straight line position.
