The PowerBlock Sport 24 is an adjustable dumbbell pair listed at 3 to 24 lb per dumbbell (about 1.4 to 10.9 kg), selected in 3 lb steps with a magnetic pin. PowerBlock says it replaces 8 pairs of traditional dumbbells, and that it cannot be expanded beyond 24 lb per hand.
This review reads the maker's specification and does not involve testing, because the site does not test products.
What does the maker say the Sport 24 is?
The Sport 24 is a block-style adjustable dumbbell with welded steel plates in a gray powder coat. PowerBlock says the plates run smooth and quiet and that colour bands on the rails match the handle's weight chart. The handle is a contoured TPR (rubber) grip, described as cushioned and less abrasive than a knurled grip. The set is sold as a pair, with a selector pin for each dumbbell. PowerBlock also says it replaces "216 lbs of free weights", its own total across the 8 pairs.

The weights are in pounds on the maker's page; the kilogram figures here are conversions. The page also states that individual plates may vary slightly from their stated values because of manufacturing tolerances. PowerBlock lists an optional Sport 24 Straight Bar, sold separately, that turns the dumbbells into a barbell.
What is the weight range of the PowerBlock Sport 24?
PowerBlock lists 3 to 24 lb per dumbbell, in 3 lb steps, which is about 1.4 to 10.9 kg. The selectable weights are 3, 6, 9, 12, 15, 18, 21 and 24 lb. Because 3 lb is about 1.4 kg, the first step doubles the load from the lightest setting, which is a point to weigh if you want very small increments.
Can the PowerBlock Sport 24 be expanded?
No. The maker states that the set does not expand beyond 24 lb per hand and that Sport EXP expansion kits are not compatible. Anyone who expects to outgrow 24 lb per hand should treat that as a ceiling, not a starting point.
Who does the specification suit?
A 10 inch block with a 24 lb ceiling suits a buyer with limited space and lighter loads, since 8 settings are packed into a footprint of about 25 x 14 cm per dumbbell. This is reasoning from the figures, not from use. The set does not suit anyone expecting to progress beyond 24 lb per hand on a single dumbbell.
PowerBlock's own FAQ says the set is suited to beginners, high-rep training, rehab or physical therapy and light warm-ups, and describes the 32 mm grip as ideal for small to average hands. These are the maker's marketing statements, so ask a qualified professional about whether a set is suitable for a health condition or injury.
Is the Sport 24 suitable for beginners?
It starts at 3 lb per dumbbell, which is a light starting load on paper, and PowerBlock lists beginners among the users it is suited to. For advice on weights and technique, ask a qualified professional; the NHS suggests starting light, such as filled water bottles for a biceps curl, and progressing gradually. See the dumbbell weight guide for beginners for how to think about loads.
What do the size and design imply for your space?
The block is far shorter than a conventional dumbbell, which reduces the storage footprint. Two blocks side by side take about 28 cm of width at the stated 14 cm each, reasoning from the stated size. Surfaces matter when setting weights down; see home gym flooring and small apartment home gym setup.
The squared block shape and the lack of a knurled option are design facts from the maker's page. How they affect a particular exercise is a personal judgement the site cannot assess.
Does the PowerBlock Sport 24 include a stand?
No stand is included according to the maker's page. The description mentions a small compact stand but gives no price or link for one. A separate PowerStand 2.0 is listed for dumbbells up to 50 lb, but the page does not say it fits the Sport 24, so confirm compatibility with the maker before ordering any stand. Without one you will need a shelf or a bench-side spot.
What warranty does the Sport 24 have?
PowerBlock lists a 5-year limited warranty for residential use only, and a footnote says it does not apply to commercial use. The page does not set out what the warranty excludes, so ask the seller for the full terms.
How does it compare with the alternatives?
Against the Bowflex Results Series 552, the Sport 24 has fewer settings (8 against 15), a lower top weight (about 10.9 kg against 23.9 kg) and a much smaller block (about 25 cm long against 43 cm). It also has a longer stated warranty, at 5 years limited against the 552's 2 years parts only on bowflex.com, though the PowerBlock warranty is limited to residential use. Its indicative price is around a third of the 552's. These are specification differences, not a verdict on quality.
What to check before buying
- Top setting. 24 lb per dumbbell, with no expansion.
- Warranty scope. Residential use only.
- Pair or single. The maker sells the set as a pair. Confirm that the listing price covers a pair.
- Stand. Not included.
- Delivery and returns. The maker's page describes shipping to the contiguous US states and gives no return policy, so check UK delivery and returns with the UK seller. GOV.UK business guidance says online customers can cancel up to 14 days after delivery without giving a reason.
- Selecting weights safely. The page includes no manual or safety instructions, so read the manual that comes with the set and ask a qualified professional about loading and technique.
Who should skip the Sport 24?
Buyers who expect to lift more than 24 lb per hand in a single dumbbell should skip it, as should anyone who wants a stand in the box. The Bowflex SelectTech 552 offers 15 settings and a higher top weight at a higher price, and the Bowflex 1090i goes higher still. For adjustable kettlebell options see the PowerBlock adjustable kettlebell review. For the wider comparison read adjustable dumbbells in the UK and budget dumbbells.
What is the price context?
The indicative price in our data is around £205 (checked Oct 2026). Check what the listing includes, since the maker sells attachments such as the Sport 24 Straight Bar and stands separately, and these add to the total. Retail prices move, so check the retailer's current price.
