How do I choose the correct size ball?A Stability Ball when sized properly makes for an active chair when sitting at a desk, keeping your core engaged, preventing and rehabilitating back injuries while improving posture. The general guidelines in choosing the correct ball size are:
Deflate the ball until your body is aligned so that when sitting your knees are at a right angle and your thighs parallel to the ground. If you are close to a cut-off point, opt for the larger size and deflate accordingly (this will also lead to a more comfortable chair).
How do I inflate my ball?- Remove plug from ball with double pronged lifter
- Attach plastic needle to pump (on some pumps the needle is stored in the handle; remove small plug on end of plunger to locate storage compartment)
- Insert needle, inflate to desired firmness and replace plug
Note, for full inflation inflate ball, allow to rest for 2 days, and then complete inflation to ensure that ball is the proper size.
