From all the date we collated, we were able to calculate the following:

an average cost for the set (2.5-40kg) as £2,078.39

An average cost per kg as £3.12

Comparing this to the cost of a set of adjustable dumbbells

the 4kg-41.5kg retails at £699

With an average cost per kg of £0.59

Or as it is currently on discount at £550 it has a Price per kg of £0.46

This shows that at retail price the an average set of fixed weight dumbbells will be 5.29 times more expensive per kg than the Stealth Adjustable Dumbbells.

or 6.78 times more expensive at the current discount.

On this page we show the data we have used in a price comparison between fixed weight dumbbells and the Stealth Adjustable Dumbbells.

We have compared both Hex and Round variations of dumbbells from 20 different sources to determine the average cost per set (2.5kg - 40kg in 2.5kg increments) and also the price per kg (£/kg) in order to generate a comparison against the 4-41.5kg Stealth Adjustable Dumbbells.

The weight options for a set of 2.5kg-40kg consist of a pair of each of the following (16 Pairs), 2.5kg, 5kg, 7.5kg, 10kg, 12.5kg, 15kg, 17.5kg, 20kg, 22.5kg, 25kg, 27.5kg, 30kg, 32.5kg, 35kg, 37.5kg, 40kg.
this totals 680kg.

The stealth 4-41.5kg adjustable dumbbells cover a weight range of 4kg to 41.5kg which offers the equivalent to a pair of each of the following (26 Pairs), 4kg, 5.5kg, 7kg, 8.5kg, 10kg, 11.5kg, 13kg, 14.5kg, 16kg, 17.5kg, 19kg, 20.5kg, 22kg, 23.5kg, 25kg, 26.5kg, 28kg, 29.5kg, 31kg, 32.5kg, 34kg, 35.5kg, 37kg, 38.5kg, 40kg, 41.5kg.
this totals 1183kg.

In order to decide which companies to use we googled the word "Dumbbells" and took the top results that supplied the vast majority of the range 2.5kg-40kg in either round or hex dumbbells, this accounted for what we believe most people would do if they were ordering a set as an alternative to the adjustable dumbbells.
On top of this we used the price from Assassin Goods as again this is a likely alternative to the dumbbells

To offer a more reliable outcome we have also opted to calculate a price per kg (Or equivalent kg) for the data.

This will be a better representation of the value as the adjustable dumbbells cover a much larger number of weight increments and therefore would be equivalent to a larger total kg.

In order to calculate this figure we simply took the package costs and divided them by the weight of the package to end up with a £/kg number

As with all tests and comparisons there are limitations.

The main ones we have come across are as follows,

1. Shipping, some companies charge shipping, some do not. we did not factor this into the comparison as it is very much address dependant, however stealth dumbbells are shipped free to UK mainland

2. Stands, we have not factored stands into the cost unless already included in the package as some companies do not offer specific stands or some just don't offer stands at all

3. This test does not address the idea that with a full set of fixed dumbbells you have the option of multiple dumbbells being in use at once, nor does it take into account the weight and volume of the set for storage and transportation purposes

Unfortunately during this test we had a number of issues that may skew the results for the package prices

Firstly, some companies don't stock the full range of dumbbells

Secondly, there were a number of sales on the products, these are likely temporary and so the prices taken are from August 2024

Finally, some companies offered packages, whereas some companies the dumbbells had to be purchases as individuals or as pairs
