Sitting on an Exercise Ball
The exercise ball can also be used as a replacement for a chair at work or home. The movement of the exercise ball requires muscular response to keep one's center of gravity and maintain balance on the ball. This stimulates the deeper trunk muscles (multifidus and transverse abdominus) that are important in supporting the spine, and reduces static loading on any one structure in the spine.
Exercise Ball for Support During Pregnancy
For pregnant women, exercise balls can be an aid in exercising while supporting the extra weight and change of center of gravity caused by pregnancy. During labor, the exercise ball can also be used to provide support for certain positions, rhythmic movement and gentle bouncing, and more.
