The MuscleSquad Rubber Hex Dumbbells 22.5kg pair is a pair of fixed-weight hex dumbbells, each listed at 22.5 kg, with a solid iron core cased in rubber and a knurled steel handle. MuscleSquad lists a 1-year warranty. The maker publishes no dimensions.
This page reads the maker's own product page on musclesquad.com and its delivery, warranty and returns terms. The site does not test products, so nothing here describes use. Where MuscleSquad publishes nothing, the page says so. It appears in the "Where to buy" block with an affiliate link to an Amazon listing; the Amazon price is around £105 (checked Oct 2026), and the listing should be checked against the maker's product page for exact match.
What does MuscleSquad say the hex dumbbells are?
MuscleSquad calls its hex rubber dumbbells a bestseller and describes them as built from a solid iron core and cased in durable rubber to protect floors and keep noise down. Its page lists pairs from 1 kg to 50 kg, and the 22.5 kg pair is one of the options in that range.
The maker gives four design points. The hex shape stops the dumbbells rolling between sets and allows floor exercises such as renegade rows. The ends are flat, which MuscleSquad says makes them comfortable for heavy pressing movements. The handle is knurled steel for grip. MuscleSquad also says they suit whole-body training, from strength work to conditioning and light cardio circuits.
These are fixed-weight dumbbells, so each pair is one weight. Anyone who wants several weights buys several pairs, which is the main trade-off covered in the adjustable versus fixed-weight dumbbells guide.

| Pair range on the page | 1 kg to 50 kg |
| Core | Solid iron |

The stated tolerance is useful when buying several pairs. Three per cent of 22.5 kg is about 0.7 kg, so a dumbbell sold as 22.5 kg could weigh roughly 21.8 to 23.2 kg on the maker's own figure. That is arithmetic from the published tolerance, not a measurement.
Is 22.5 kg per hand a sensible weight to buy?
It depends on the exercise and the person, and the maker does not give a recommendation for this weight. What MuscleSquad does say about choosing is general: a good starting point is three pairs for light, medium and heavy movements, and it suggests 2 kg, 4 kg and 6 kg pairs for beginners, or 3 kg, 5 kg and 10 kg if that sounds too light.
By that guidance a 22.5 kg pair is a heavier option, more likely to suit pressing and rowing movements than isolation work. The NHS says adults should do strengthening activities on at least 2 days a week that work all the major muscle groups: legs, hips, back, abdomen, chest, shoulders and arms. It gives no loads, so the weight is a personal decision, and anyone unsure should ask a qualified professional. The dumbbell weight guide for beginners covers how to think about increments.
MuscleSquad sells the middle of its range in 2.5 kg steps (12.5, 15, 17.5, 20, 22.5, 25, 27.5 and 30 kg), so a 22.5 kg pair sits between a 20 kg and a 25 kg pair. That spacing matters if a lifter expects to progress, because the next pair up is a 2.5 kg step per hand rather than a larger jump.
Will rubber hex dumbbells damage a floor?
MuscleSquad says they will not damage flooring if laid down and picked up carefully, but it advises training on rubber gym flooring where possible, so that dropping the dumbbells is safe and avoids scuffs and marks. That is the maker's statement, and a 22.5 kg dumbbell carries more risk to a floor than a light one. The rubber flooring versus foam mats guide and the best home gym flooring guide compare what to put underneath.
The rubber casing also addresses noise, which MuscleSquad names as a purpose. How quiet any dumbbell is depends on the floor and how it is handled, so the home gym ventilation and noise guide is the better place to plan for shared walls and floors.
What do the delivery, warranty and returns terms say?
MuscleSquad publishes more terms than many marketplace sellers, which is the main reason this page can be written from a maker source.
Delivery
- Pairs of 12.5 kg and below ship in a single box. Pairs over 15 kg ship in multiple boxes, which may not arrive together; MuscleSquad asks buyers to allow at least 48 hours for the rest before contacting it.
- Standard UK mainland delivery is free on orders over £50, with some geographical exclusions. Orders received before 12 noon are dispatched the same day, and mainland UK delivery is usually the next working day.
- Large or heavy orders go by a specialist freight courier, which contacts the buyer within 48 hours; delivery is usually 5 to 10 working days to a ground-floor room of the buyer's choice.
A 22.5 kg pair is two separate dumbbells, so a delivery is likely to be more than one box under MuscleSquad's own rule. That also applies to the Amazon listing only if Amazon ships the same product from the same stock, which the maker page cannot confirm.
Warranty
The warranty runs for one year from receipt of delivery and covers defects from normal use. Depending on the issue, MuscleSquad says it will repair the product, repair or replace parts, exchange it or offer a full refund. Exclusions include damage from negligence such as dropping the product, unauthorised modification, weather damage such as rust from keeping the product outside, theft or loss, and improper cleaning. The product must be used indoors in a temperature-controlled environment and kept dry. Claims go to info@musclesquad.com, and MuscleSquad says it will respond with a resolution within 48 hours.
The dropping exclusion is worth reading in light of the product: heavy dumbbells are the kind most likely to be dropped, and that is not covered.
Returns
Under MuscleSquad's refund policy, returns are accepted within 30 days, and the item must be unused, in the same condition and in its original packaging, with proof of purchase. Sale items cannot be refunded, and a used item can receive a partial refund at most. Refunds go to the original card and can take 3 to 10 working days. These terms apply to purchases from MuscleSquad. A purchase through Amazon follows Amazon's terms, not these, and the GOV.UK guidance for sellers says consumers can cancel up to 14 days after delivery for distance sales, with some exceptions.
How should the dumbbells be cleaned and stored?
MuscleSquad says the dumbbells may carry a coating of silicone oil, used to preserve the rubber in storage and transport, which a dry cloth removes. To clean, it recommends wiping the rubber ends with a microfibre cloth and using WD-40 on the handle to prevent rust. If an antibacterial spray is used, the dumbbells must be dried thoroughly afterwards. The warranty page adds that chemical solutions sprayed directly on the product can remove the finish, cause rust and void the warranty, so the two instructions should be read together before choosing a cleaner.
For storage, a pair of 22.5 kg dumbbells is heavy to lift from the floor, and MuscleSquad sells racks in packages with its hex pairs. Its Starter set is 2 to 6 kg in 3 pairs, the Intermediate set is 3 to 20 kg in 8 pairs with a vertical stand, and the Advanced set is 5 to 30 kg in 11 pairs with a 3-tier stand. Storage options are discussed in the home gym storage ideas guide.
What does the maker not publish?
- Dimensions of the head or the handle, so fit with a rack, a storage tier or a bench cannot be checked from the page.
- The handle diameter and length, which affect grip and whether the dumbbell suits large or small hands.
- The grade of iron, the type of rubber, or any noise or drop-test figure.
- Whether the Amazon listing linked below is stocked and supplied by MuscleSquad itself, so the warranty and returns terms above may not apply to it.
Anyone relying on a specific dimension should ask the maker before buying, using the contact details on its site.
Who should skip these?
Anyone who wants one set of weights that covers many loads in a small space should look at adjustable dumbbells instead, because fixed pairs take up space for every weight. The best adjustable dumbbells guide and the budget dumbbells guide compare the alternatives. Beginners following MuscleSquad's own suggestion should consider lighter pairs first, since 22.5 kg per hand is a heavy single purchase. Buyers who need published dimensions should also skip until the maker provides them.
How much do they cost?
The linked Amazon listing is around £105 (checked Oct 2026). MuscleSquad sells the same weight range on its own site, and prices on a maker site and a marketplace can differ, so compare the two sellers and their terms before buying. Retail prices move, so treat this as indicative.
