Stability balls are a versatile addition to your home gym, but in most cases will arrive to your home deflated in a flat box. The size of your ball will depend on the size you've purchased, so you can use the ball measurement to ensure you inflate your stability ball to the right size. If your stability ball didn't come with a pump kit, you can use a regular basketball pump or even a gas station air pump to fill the ball and get started.

Step 1

Remove the stability ball from its box and packaging. Inspect for any apparent rips or tears before you inflate the ball. Read the front of the packaging material, which will tell you how large the ball should be when inflated. Stability balls usually come in 55 cm, 65 cm and 75 cm sizes.

Step 2

Measure the size of the ball you've purchase on a wall with a measuring tape. Mark the size with a pencil, which will serve as a general, if inexact, way to measure the ball's inflation. The final measurement will take your own preferences into account.

Step 3

Insert the pump needle into the ball opening and begin to pump. SPRI, a stability ball manufacturer, suggests filling the ball to 50 percent, capping the opening and leaving the ball overnight to settle.

Step 4

Remove the cap in the morning and reinsert the pump pin. Continue inflating the ball, stopping when you reach the pencil mark on the wall. Cap the ball and take a seat. Keep in mind that the more inflated a ball will be, the more difficult it is to balance and the more difficult your workout will be. If you're just beginning your stability ball regimen, fill the ball a little less. If you're looking for a higher intensity workout, fill the ball to its full size.

Step 5

Keep the pump kit somewhere safe, as you will need to re-inflate the ball from time to time. If possible, leave the size mark on the wall and measure your stability ball against the mark weekly so you know when you need to add more air.
