Rank #5 in Best Adjustable Dumbbells 2026: 10 Ranked, Pair or Single
POWERBLOCK Sport 24 Adjustable Dumbbells, Pair
Price and rating as shown on Amazon when we collected them. Both change.
The POWERBLOCK Sport 24 matches the best rating in this ranking at 4.7, from 558 ratings, and it does it with the most compact dumbbell shape here: 25.4cm long, which is why owners keep saying it takes up no space. At £179.00 for a pair reaching 11kg per hand, it sits between the DH FitLife pair and the ATIVAFIT on price while giving up ceiling to both.
The reason it is not higher is the ceiling itself. Eleven kilos per hand is the second lowest maximum in this guide, and it is reached across a narrower span than the sets above it. The specification table repeats the fault of the category: the box contains two dumbbells, but the published item weight of 10.9kg is the weight of one, so the number that is supposed to reassure you does not.
How those 558 ratings break down
An average hides its own shape. This is the spread behind the 4.7 stars.

Questions people ask
Is it a pair?
Yes: the set contains two dumbbells in the box, and the listing describes them as supplied as a pair.
What is the maximum weight per hand?
11kg, the second lowest ceiling in this ranking, which is why it sits mid-table despite a 4.7 rating.
How big is it?
25.4cm long with a 32mm handle, making it the most compact adjustable dumbbell in this guide and the easiest to store.
How is it rated?
4.7 from 558 ratings — the joint highest score here, with eighty-three per cent of buyers at five stars.
Is the item weight a check on the pair?
No. It reads 10.9kg, which is the weight of a single 11kg dumbbell, so it cannot be used to confirm the pair.
