Rank #5 in Best Slam Ball 2026: 9 Ranked, and the Labels That Don't Add Up
Core Balance No Bounce Slam Ball, 3kg to 10kg
Price and rating as shown on Amazon when we collected them. Both change.
The Core Balance Slam Ball sits fifth in this guide. It is sold in four weights — 3kg, 5kg, 8kg and 10kg — with the 10kg version priced at £21.24 and rated 4.4 out of 5 from 242 ratings. Where several other listings in this guide have a title weight that disagrees with the spec sheet, this one largely holds together: the first bullet is headed "10KG SLAM BALL", the Size field reads 10kg and Item Weight reads 10 kg. The oddities sit elsewhere. The Colour field reads "10kg", which is a weight rather than a colour, and the spec sheet carries a field marked "Tennis Ball Duty Rating" reading "Extra Duty" — a rating for tennis balls, on a slam ball. The listing also sits at number 2 in Medicine Balls in Sports & Outdoors.

Questions people ask
Which weight is the Core Balance slam ball in this listing?
The first bullet is headed "10KG SLAM BALL", Size reads 10kg and Item Weight reads 10 kg. The title also lists 3kg, 5kg, 8kg and 10kg, so it is worth checking which variant is selected before ordering.
Does the Colour field tell me what colour it is?
No. The Colour field on this Core Balance listing reads "10kg", which is a weight rather than a colour. The bullets say each weight has its weight labelled in a coloured circle.
Will it bounce back or roll away from me?
The bullets describe a no-bounce design filled with sand, which they say removes the danger of it rolling away or bouncing back towards you.
What is the "Tennis Ball Duty Rating" on this slam ball?
The Core Balance listing carries a spec field reading "Extra Duty" under Tennis Ball Duty Rating. That field is for tennis balls and tells you nothing about a slam ball.
What is it made from?
Material Type reads Polyvinyl Chloride (PVC) and Construction Type reads Single Layer Molded. The bullets describe a hardwearing PVC shell and a dimpled surface for grip.
How is it rated by buyers?
4.4 out of 5 from 242 ratings. The displayed breakdown shows 66% of ratings at five stars and 3% at one star, and the listing ranks 2 in Medicine Balls in Sports & Outdoors.
