How To Put Air Back Into Yoga Ball

Yoga, or stability, balls come in different sizes based on your height and leg length. Denise Austin, author of "Sculpt Your Body with Balls and Bands," suggests choosing a ball that allows you to sit with your feet on the ground and your knees bent at a 90-degree angle. You should not inflate the ball any larger than its diameter. However, Austin says check the ball once you inflate it to ensure it gives, or pushes in, about 2 to 3 inches and adjust the ball accordingly.

Step 1

Remove the plug from the yoga ball. The plastic plug measures approximately 1 to 2 inches long, with a dime-size head. The shape of the plug is much like a large plastic nail.

Step 2

Look for the diameter size of the ball, listed on the yoga ball next to the plug. Make a small mark on a wall that equals the diameter of your yoga ball.

Step 3

Attach a cone-shaped nozzle pump adaptor to the hose of an air pump, hand pump or air compressor. Insert the nozzle into your yoga ball.

Step 4

Pump air into the ball until it reaches the mark you placed on the wall. Quickly remove the pump nozzle and insert the plug, to lose as little air from the ball as possible.
