Fitball Exercises for the Stomach

Fitballs are inflatable balls with a diameter of between 18 and 30 inches. Used by physical therapists in Switzerland for rehabilitation, fitballs were introduced into the U.S. in the 1980s. Personal trainers use the fitball to help clients build strength.

  1. Reverse Curl

    • Lie with your face up and hold the ball between your feet. For support, place your hands between your lower back and the floor. Lift your tailbone off the floor, pulling your pelvis towards your chest.

    Knee Pull-In

    • In push-up position, place your lower legs on ball and hands on the floor. Pull the ball towards your head by bending your legs. Continue until your thighs are near your chest, then release slowly.

    Lumbar Roll

    • Lie face up on the floor with your legs bent at a right angle. Place the ball beneath your legs and extend your arms with your palms up. Slowly roll the ball to the left and right without lifting your shoulders off the floor.
