Rank #9 in Best Slam Ball 2026: 9 Ranked, and the Labels That Don't Add Up
JLL Slam Ball for Home Gym, 12kg
Price and rating as shown on Amazon when we collected them. Both change.
The JLL Slam Ball for Home Gym is a 12kg sand-filled rubber ball sold as a no-bounce tool for slams, squats and lunges. It takes the number 9 spot in this guide, priced at £29.99, with a 4.6 out of 5 rating from 53 Amazon customer ratings — 76% of them five-star, and not one of them a one-star.
The weight is where this listing gets awkward. The title, "JLL Slam Ball for Home Gym High Impact Workout - No Bounce", never names a number at all. You have to reach the specification table to find 12kg, and there it appears three separate times: Item Weight 12 kg, Size 12kg and Colour 12kg. A colour field reading "12kg" tells you nothing about what colour the ball actually is. The other counts do line up with each other, though — Number of Items is 1 and Unit Count is 1 count, so nothing here is quietly selling you a set. Everything on this page is taken from the Amazon listing, not from any testing we carried out.
How those 53 ratings break down
