Inflate ball to 80% of its stated size. If ball feels hot or cold, allow it to come to room temperature before starting the inflation process. 2. Leave for 24 hours before inflating to full size. Then measure to ensure ball is properly inflated. 3. After the ball has been inflated, insert the provided plug into the hole and press firmly so no air escapes. 4. The sizing of each ball is to provide the user a guideline when purchasing the Wawavita fitness ball. Note: The size 65cm and 75cm are the absolute maximum size of each ball. At this level of inflation, the ball may be too firm for comfortable use. 5. To determine the correct sizing, perform this simple test: Sit on the ball and place your feet flat on the floor. If the fitness ball is inflated correctly, there will be 90 degree angel between your hips and knees. Adjust the fitness ball by adding or releasing air without exceeding maximum size. If you reach the 90 degree angel, the ball has sufficient air, even if not at full size.
