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.
