The 66fit Slam Ball is the number one pick in this guide to the best slam balls. It is a PVC-shelled ball with a sand and iron mix core, sold as a no-bounce weight for slamming into a wall or the floor. At £20.50 it carries a 4.7 average from 1,008 ratings, and it sits at number 15 in Amazon's Medicine Balls category.

Where this listing gets interesting is the weight. The title stretches across three sizes — "5, 10, 15kg" — and the final bullet repeats that range. The specification fields do not. Size reads 10 kg, Item Weight reads 10 kg, and the item type name spells it out as "66 Fit Slam Ball - Black, 10 kg". Number of Items is 1 and Unit Count is 1.0 count, so this is one ball rather than a set of three. One more field is worth knowing about before you buy: Sport Type is listed as Tennis, while the brand's own bullets describe a ball for explosive strength, speed, stamina and boxing workouts. Everything on this page comes from the Amazon listing, not from any testing we carried out.
