MDUSA is proud to introduce THE SLAMMER! Every aspect of The Slammer was designed around a single movement, The Slam Ball. The shell, weight medium, air pressure, and dimensions are the result of extensive product development performed over a range of environments. We believe we have created something unique that will eliminate the frustrations of current commercial products while providing years of physical pain and suffering to its users. Just say no to Corks! We didn’t cut the cork, stuff the cork, or glue the cork. We eliminated the cork. Many current products used for the slam ball movement make use of a plastic rim and cork system. Slamming a ball repeatedly at the wrong angle will cause the product to fail at or near the rim. By working closely with material specialists we were able to create both a product and process that allows for the same super tough 9” diameter shell to be weighted at 10, 15, 20, 25, or 30 pounds and 10" diameter for the 35, 40, and 50 pounds without the use of a cork system. Tested tough. This ball has undergone an incredible gauntlet of testing. We did our best to run this ball through the unknown and the unknowable but it still came back for more slams. In fact several of our prototypes have been slammed over 5000 times and are still on active duty. That’s why we are confident in making the below UNCONDITONAL GUARANTEE;

works well
The ball is definitely designed for slamming. It is tough and so far took all the throwing and slamming I can deliver without any issues. Perfect since it doesn't bounce much at all even if I put my entire weight into it and slam it down from a jump. It wouldn't bounce into my face but still enough so I can catch it. Two of them works great for push ups too since they are the same size regardless of weight (I got the 15 lb also). Use them to improve depth of the push up and improve hand/wrist strength at the same time. It can feel a bit slippery though, because of its tough and harder rubber like surface. But haven't caused any issues so far. Wish they would make more colors so I don't have to hunt for the weight number.

Manufacturer's 3 year guarantee does not apply if you buy through this seller
I have purchased several Muscle Driver Medicine Balls of various weights, and in general I really like them, and would give them five stars.The reason I am giving this one three stars is that after about 6 months my 35 lb ball lost its air, which makes it feel very hard and lumpy and uncomfortable to use. If you buy these balls directly from MDUSA they come with a 3 year guarantee. I contacted the seller for this product, but apparently the 3 year guarantee does not apply if you buy it from them. After going back and looking at the product page, I see that they did not say the guarantee was good for 3 years like it does on the manufacturer's website, so I guess that is my mistake. This is an expensive product, so in the future I plan on buying them directly from the manufacturer where I can get it for about the same price with the 3 year guarantee.

best workout purchase yet
My brother who's a PT introduced me to smash balls and once I got one I have been hooked. It is an integral part of my workouts. The 20lb for me is perfect as it provides a fairly quick transition into anaerobic exercise. Anything over 25lb would probably be too heavy for me (6' 200lbs, decent build). I use it like a medicine ball as well as lots of smashing on the ground. You'd be surprised how quickly you end up out of breath.

Very little bounce
This ball has sand inside the core (instead of solid rubber core). I think it makes the ball stop bouncing when it slams on the ground. It is fairly difficult for wall ball exercise.However, it's a good quality ball, the sand inside is just too weird for me.

I am very happy with this ball
I am very happy with this ball. I was looking for one with a slight bounce for quicker reaction and this has exactly that. Durable and great for ball slams.
