One of the pro basketball players broke his arm when doing weight lifting (dumbell presses) while lying on an exercise ball. These large vinyl balls, frequently found in gyms, are often used instead of a bench.
The ball just "exploded".
Just a "head's up" for those who use this equipment:

Like any other piece of equipment, they have a weight limit. If the user doesn't know what that is, and overloads it, hey...it's their fault. Too bad.
But seriously folks ... I can just see balance balls being taken off the market as unsafe. All because some lame brain can't figure out that he + his equipment weigh more than the ball's capacity.

Concern is noted...
Now, the Fitness Ball is rated for a 600 lb weight capacity. The basketball player weighed 195, and he was lifting 90 in each hand. So he was at a total load of 375 lbs, quite a bit under the capacity of 600 lbs.

Yeah, but take into account the forces created by dropping/lowering the weights each time to begin each rep, and the subsequent additional pressures involved when pushing them upwards could very well push the total amount of PSI pressure on the ball well past its breaking point. You can stand on a scale that shows you weigh only 180lbs, then suddenly drop your weight without jumping and you will see the scale shoot past 200 - 250 pounds or more. We are dealing with a rubber ball, not welds here, and Im sure he (and other Kings players) were using this ball for a while which could have stretched and compromised the structural integrity of the rubber.
Bottom line is dude was stupid to use an exercise ball with 90lb dumbbells.

To built stronger core, this is an excellent drill. A must for a swimmer like me, especially butterfly sprinter.
This is not stupid drill, a beautiful drill instead. I used it both in my home gym and in the real gym.
Now I know that extra caution should be raised when I use those ball.
