Jam Ball
The Extreme Jam Ball is an excellent tool. Good grip, easy to handle.

A great slam ball
I really like the PB Extreme Jam-balls because they are easy to grip, they take a lot of abuse and they don’t leak. I’ve used them in my HIIT classes for about 8 years now and we still are using the originals I purchased.

A Slam ball and COMPANY you can depend on!
These Jam Balls Are a staple at our gym. We have various sizes and our clients LOVE them. It is also nice that Perfom Better will repalce the ball if it breaks! I had one ball that started to leak, I sent them a pic and video and I had a new ball back in my gym in just a day or so!

PB Extreme Jamball
I was incredibly disappointed in this slam ball. It is not sized well for the material inside. It is very unbalanced. Can be used for slamming to ground, but not even very good for that purpose. Hard to control because of this imbalance. Check out another site for this item. Total waste of money.

perfect slam ball, but 20lb ball too large?
The ball's main function, to be slammed, works great. It is strond and durable. Only thing is, the 20 lb ball is very large, yet only filled about 1/3 of the way, so the bladder seems bigger than it needs to be. The 10lb ball is NOT too big, it's perfect.
