Rage Fitness Slam Ball, Ideal for Cross Training, Core Exercises, Plyometric and Cardio Workouts

This thing is durable. Been slamming in the mornings on concrete slab. Great product.

I really like having this to smash around :) It's so fun. The one annoying thing is about every 3 or 4 smashes, I have to refill the air inside the ball. If I don't, the air pushes out and all the sand gets hard and won't smash as nicely.Either I smash too hard for the ball or the ball cork has a weak seal.

Not kidding, this thing fits every need of mine. I’ve already used this thing so much and it’s kept together better than I could’ve ever expected for something at that price point.

The media could not be loaded.  I bought a couple of theses balls at one time. Half of them are perfect and the other half don’t hold there shape.

This slam ball is well balanced & is a perfect size.Not too big so you can't control it, but not so small that you can't use it for exercises that require you to lean or push off of it.It will lose air after time, but no issue. Just inflate with bike pump or air compressor.I got the 20lb size thinking it might be too light. But it kicks my butt!Great product that will give you an intense (and different) workout.

This thing is heavier than I would have expected at 30lbs so you need to be careful with it, but it works well at shredding your core. Zero bouce so if you are looking for that type of training a different version would be better suited. But I like it quite a bit.

Purchased the 30lb ball 10 months ago, as of last week, this ball is completely worthless. The port for adding air popped out and can not be the-inserted. I don’t know if it was just a fluke or a flaw... but it is well beyond the return date and I’m out of pocket the cost of another. I will buy from a more well known source on my next one.

Hubby and I wanted one like we use at our fitness bootcamp we attend, so we got the 15 pounder. YES, it is rubber (outer shell) and YES, it smells like rubber. Have you been to a gym lately? This thing built to last, takes a beating and the smell does dissipate after a while, so don't worry too much about it. Grip is good, could be better BUT.. this isn't a tire, and we've had no problems with it slipping. DOES NOT BOUNCE! Which is why we like it ;-) The 10 pound would have been too light for me and hubby (we've been loosing weight and working out regularly), and the 15 pound is JUST RIGHT if you've been using one for 2 - 3 months. Gives enough resistance / challenge on the arms without being too much for us. Hope this helps.

Used it today and it was exactly what I wanted it to be. Doesn’t bounce so you can put maximum effort into slamming it into the ground.

Helps with tough days, dealing with the anger and anxiety I am currently experiencing

Great product. Awesome to slam. Definitely the rounded out my home gym nicely.

Got exactly what was described
