PB Extreme Jam-Ball Medicine Balls are great for slams or exercises when you don't want the ball to bounce. They are durable and soft medicine balls that are sand-filled, and feel like they're filled with gel.

Ratings & Reviews
A great slam ball
by Steve Auferoth -
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!
by Tricia Jones -
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!
Best all around workout!!

"I've found slammer ball workouts to be exhausting,
And just about the most effective core-strengthening exercise I've done. Similar to kettle bells, but
Unlike kettle bells there's less momentum to help
You. I'm a very fit 220lbs guy, after a few minutes with
A 30lbs ball, I'm winded!"
Broken Jam Balls
by Nick Keenan -
While the jam balls have been very effective in our speed and strength program, 3 out of the 4 25lb balls broke 14 months after they were purchased. The manufacturer has only a year warranty. With them being $45 a piece, they don't seem to be worth the money if they need to be replaced every year.
Great Workout Tool
by Montrell W -
I have incorporated this ball into my personal workouts as well as with my clients and it has proved to be a useful tool.
PB Extreme Jamball
by Christy -
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?
by Tovi E -
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.

love that they don't bounce, extra work to pick it up.
Wish they were better quality
by Alan D
I love the idea of these balls. I even like the fact that the balls seem oversized for the amount of fill - slightly awkward, but good for motor control. And they work great, for a while. Unfortunately, they don't last. We frequently get pinhole leaks in the ball, or even worse, large leaks at the valve, which then causes a significant spewing of the sand on each slam. They are rather costly for a product that doesn't last.
