Bursting balls!


EB Brands on Thursday voluntarily recalled three million fitness balls made in China after reports that they can pop unexpectedly if overinflated -- despite the fact that the products specifically say they are burst-resistant. Bally Total Fitness, Everlast, Valeo and Body Fit Fitness Balls, all made by EB Brands, are involved in the recall....

...What's more, the executive of advocacy group Kids in Danger said, "They're big bright colorful balls," meaning they're alluring outside of exercise class.

"If you've got one and you've got kids, your kids are definitely on them in addition to the more organized use of them," Cowles said.

Re: Bursting balls!

Yes, the ball should only be inflated to small values of pi.
For example, the 65 cm ball should not be inflated beyond a circumference of 204 cm (204/65 = 3.138)

If you do not have the measuring tape that came with the ball, you can also use a tape measure of your own. When measured around the center of the ball, the circumference should be as follows: Diameter: Circumference (around center of ball):
55cm ball (22 inches) 172 cm (68 inches)
65 cm ball (26 inches) 204 cm (80 inches)
75 cm ball (30 inches) 235 cm (92 inches)

DO NOT use the ball if it is over inflated or expanded to a size greater than the correct size.
