5'6" to 5'11" Medium: 65cm/26"
6'0" to 6'3" Large: 75cm/30"

Stel'Air Stability Ball FAQ's

How to choose the correct size exercise ball

If using the ball as a chair the ball should be inflated more than if being used for exercises. When seated for long periods it is healthier to have the legs at a wider angle from the body for improved breathing and digestion.

With the ball inflated more, the hips will be above the knees. This opens the hip joint to help reduce the strain on the internal organs that long term sitting can do.

When exercising the legs at a 90 deg angle will keep the knees and hips in alignment. The thigh is parallel to the ground so exercises like abdominal crunches effectively engage the core and are comfortable.

How to inflate a fitness ball

When you first get the stability ball in the mail it will be folded into a small box. Especially important in the winter is to open the box and allow the ball material to warm up to room temperature before unfolding.

Once the ball has warmed up then inflate the stability ball just to the point where the material begins to stretch slightly.

Leave the ball to relax at that point overnight before filling to the desired size.

DO NOT over-inflate.

How to repair a leaking stability ball

If there is a flaw in the stability ball from manufacturing it will show up right away. Common reasons for losing air is the ball plug isn't in tight enough or there is a small hole somewhere in the material.

Depending on the amount of use it is not unusual to have to add air to the ball on a weekly or monthly basis.

Keep the ball use in a clear area to avoid possible sharp objects. Also make sure your pockets don't have anything that can puncture the ball material.

If for whatever reason you have a damaged ball, it cannot be repaired safely.

Caring for your Stel'Air Stability Ball

  • Use on a smooth and level surface. Do not use on gravel or dirt.
  • Balls are easy to clean with warm water and a little mild soap. Be sure to thoroughly rinse soap off and dry with an absorbent towel by lightly patting.
  • Be sure to empty trouser pockets prior to use especially things like keys and pocket knives.
  • Any scratch or nick in the ball material can compromise the safe use of the ball and should be replaced.
  • Keep the ball away from heat sources like a radiator and away from open flames.
  • When not in use, store the stability ball out of direct sunlight.
  • Individual use only. This item was not intended or designed for multiple-users.
