The Exersci Hex Dumbbells 20kg pair is a pair of fixed-weight hex dumbbells, 20 kg each, that Exersci describes as rubber-cased with contoured steel handles and a hexagonal head to stop rolling. Exersci gives a 1-year guarantee. It publishes no dimensions.
This page reads Exersci's own product page and its terms, delivery and returns pages. The site does not test products, so nothing here describes use. Exersci's page sells several weights under one listing, and the 20 kg pair is one variant of it. No price is given here because no indicative price has been checked for this product; check the current price on the retailer's page.
What does Exersci say the hex dumbbells are?
Exersci calls them its Premium Exersci Hex Dumbbells. The maker states that the heads are encased in rubber to increase durability and lifespan, and that the handles are made of contoured steel for a comfortable grip. It says the hexagonal head on each end is there to keep the dumbbell stationary after use, so it does not roll.
The page is sold as pairs, so the 20 kg option means two dumbbells of 20 kg each, 40 kg combined. That total is arithmetic from the pair listing, not a published figure. Exersci also sells hex dumbbell bundles and dumbbell tree sets, which are different listings with different weights.
Fixed pairs suit buyers who know the load they want. Anyone who prefers one set for many loads should read the adjustable versus fixed-weight dumbbells guide first.

The page text says there are 20 weight options starting at 2.5 kg and rising in 2.5 kg steps to 50 kg. The variant selector on the same listing shows more options than that sentence suggests, including 1 kg to 9 kg and up to 60 kg, so the written range and the selector do not match. A buyer who wants a weight at either end should confirm it is in stock with Exersci.
Is a rubber-cased hex dumbbell a good fit for a home gym floor?
Exersci says the rubber casing is for durability and longevity. It does not state that the casing protects floors or reduces noise, and it publishes no drop-test figure, so those benefits are not supported by the maker page. Rubber is generally gentler on a floor than bare iron, but a 20 kg dumbbell dropped on a hard floor can still mark it, and that is reasoning rather than a maker claim. Guidance on what to put underneath is in the rubber flooring versus foam mats guide and the best home gym flooring guide.
The hex shape matters for the opposite reason: Exersci says it stops the dumbbell rolling, which is useful on a floor where a round dumbbell could roll into furniture or a skirting board. Noise is a separate planning issue for shared walls, covered in the home gym ventilation and noise guide.
Is 20 kg per hand the right weight to choose?
The maker does not recommend a weight for this option. 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. A heavy pair like 20 kg per hand is more likely to suit larger movements such as presses and rows than small isolation work, which is a reasoned view, not a maker statement. The dumbbell weight guide for beginners explains how to choose starting weights, and a single weight is rarely enough. Because Exersci sells pairs in 2.5 kg steps, a 20 kg pair sits between 17.5 kg and 22.5 kg options, so a later step up is a small one.
What do the delivery, guarantee and returns terms say?
Delivery
Exersci's shipping policy says its products ship on a free next-day service with FedEx, Evri or Royal Mail, with same-day dispatch for orders placed before midday where collection has not already taken place. Orders to Northern Ireland and the Highlands may take 2 to 4 working days. The terms state free postage on orders over £100 for the UK mainland only, which differs from the shipping policy's wording, so the delivery charge for a single pair should be confirmed at checkout. If the courier asks for a signature, the terms say to check the condition of the product and packaging, note any damage with the courier, sign for the parcel and then tell Exersci rather than refusing it.
Guarantee
Exersci's site says all its products carry a 1-year guarantee. The terms say the warranty covers manufacturing faults and that Exersci can give help by phone or arrange a repair or replacement of a faulty product. It excludes normal wear and tear on certain parts; the examples it lists are for other equipment, such as treadmill belts, and none is listed for dumbbells. The terms do not say whether dropping damage is excluded. Anyone with a concern should ask Exersci before buying.
Returns
Exersci offers a 30-day money-back guarantee on unused products. The buyer emails the company within 30 days of ordering, and the items must be unused, unbuilt and in their original packaging. The team says it replies within 24 hours with instructions, and buyers should wait for those instructions before sending anything back. This is separate from rights under consumer law; the GOV.UK guidance for sellers says distance-sale customers can cancel up to 14 days after delivery without giving a reason, with exceptions.
What does the maker not publish?
- Dimensions of the head or handle, so fit with racks or dumbbell trays cannot be checked.
- A weight tolerance, which matters when buying several pairs.
- The core material. The page describes rubber-cased heads and steel handles but does not say what is inside the rubber.
- Whether the casing is intended to protect floors or reduce noise, or any drop-test figure.
- The full text of the guarantee for dumbbells specifically.
How does it compare with other options?
The comparison here is limited to what Exersci publishes. A pair like this suits buyers who want a simple fixed load and are prepared to store separate pairs. The budget dumbbells guide compares ways to spend less, and the best adjustable dumbbells guide covers the compact alternative. For storage planning, see the home gym storage ideas guide, since Exersci sells dumbbell trees as separate products and a pair of 20 kg dumbbells is heavy to lift from the floor.
Who should skip this pair?
A buyer who needs published dimensions to plan a rack or storage should skip it until Exersci provides them. A buyer who wants one purchase to cover a range of weights, or who has very little storage, is better served by adjustable dumbbells. A buyer who wants noise and floor claims backed by a figure should look for a maker that publishes one. Exersci's page gives no evidence on either point.
