exervo GS 65cm exercise ball

exervo GS 65cm Exercise Ball

$29.99

Our new GS series exercise balls are extra strong plus safety tested and certified

The exervo™ GS series exercise ball is made with 28% more material in the 65cm and 75cm sizes and 10% more in the 55cm size than one of the leading exercise balls on the market today. Our GS exercise ball carries the internationally recognized TUV GS Mark- from the German equipment safety law and is available for only approved products. The mark means the product has been tested and certified for safety and that continuous product and production control is maintained.

By using more material in the manufacturing of the exervo GS balls safety is enhanced since if the ball is ever accidentally punctured it will slowly and safely deflate. In fact, we tested this exercise ball to measure the slow deflated rate by puncturing a correctly inflated 65cm GS ball with a scissors with a 170 lb person sitting on the ball. Upon puncture it took the ball over 20 seconds to fully deflate rather than burst or blow out in a matter of seconds. More material means a thicker ball which translates into reducing sudden and unexpected ball deflation.

Inflation Instructions and Care

Inspect
Please do not open your package with a sharp object. Remove the ball from the packaging and inspect for any damage that may have occurred during shipping. It's normal for the ball to have slight creases (fold marks) when first inflated. Make sure the ball is at room temperature before proceeding.

Inflate
inflating the Gymnic or Fitball exercise ball Remove the plug from the ball. Do not use a sharp object to remove the plug. A coin (quarter) can be used to raise the plug enough to pull it out. The manufacturer includes a packet containing the plug and a pump adaptor. The adaptor is made for bicycle pumps, which can be used to inflate your ball. However, bicycle pumps are designed to inflate small items to a high pressure. Exercise balls have a large volume and a low pressure. Pumps designed to inflate large items work best on exercise balls.

The balls are inflated according to size, not pressure. Never inflate the ball larger than the recommended diameter. Each ball has the maximum diameter (width) printed on it in centimeters and inches. To insure proper inflation, place the un-inflated ball between two flat, upright surfaces, such as a wall and a box. Make sure the box is the same distance from the wall as the ball's diameter. Inflate the ball until it just touches the 2 surfaces.

Care

Contents: One exervo GS65 cm exercise ball and one free inflation pump included with each order (regardless of quantity).
