Clinical observations involving the use of a stability ball with prenatal clients have shown a “low incidence of back pain in late pregnancy, strong, firm abdominal muscles and increased core stability.” Due to its dynamic nature, exercising with the stability ball will improve posture, balance, coordination and body awareness. Almost every exercise works the “foundation” or trunk, even when working the extremities. These benefits are especially important for the prenatal population as certain anatomical changes of pregnancy (i.e. change in center of gravity, joint laxity, etc.) are known to precipitate negative effects on the pregnant body. Exercising with the stability ball throughout pregnancy will help minimize or alleviate these potential effects. This hands-on course will provide practical instruction on selected strength and flexibility exercises, utilizing both the ball and tubing, appropriate for the prenatal client. Screening techniques, physiological and anatomical changes and resistance training guidelines will also be reviewed.
