"Exercising with a stability ball improves balance,
strengthens abdominal and back muscles
and improves body awareness..."
Stability ball guidelines:
* Make sure you maintain proper air pressure.
When the ball is firm, the exercises are more difficult.
When the ball is soft, the exercises are easier.
*Knees and hips should form a 90 degree angle
when seated on the ball.
*Using a ball for your desk or office chair forces you
to sit up straight..
It will help strengthen your core (back and abs)
*Size does make a difference.
Appropriate ball sizes:
Height Ball Size
5 ft. 45 cm
5 ft- 5'7'' 55 cm
5'8-6'2" 65 cm
6'2" and taller 75 cm
