Guidelines for Choosing a Stability Ball
These stability ball guidelines will help you to select the right size. It is important to buy the right size stability ball and maintain the proper air pressure. The firmer the ball, the more difficult the exercise will be. The softer the ball, the less difficult the exercise will be. If you are just beginning, overweight, an older adult, or you are generally deconditioned, you may want to consider using a larger, softer ball.
When sitting on the ball, your knees and hips should align at a 90-degree angle. Following are general guidelines for buying the right size stability ball:
Under 5' 45 cm ball
5' to 5'7" 55 cm ball
5'8" to 6'2" 65 cm ball
Over 6'2" 75 cm ball
Procedure for Inflating Your Stability Ball
1. Attach enclosed adaptor to a standard air pump and insert into ball.
2. For the 55" ball: inflate until the ball reaches 21" in height; for the 65" ball: inflate until ball reaches 25" in height.
3. Insert enclosed cap to seal
