Who Is Level40FitnessUK?
Level40FitnessUK is a UK-based fitness YouTube channel focused on practical home training, equipment reviews and strength programming. Their content is aimed at people building serious home gyms in the UK — covering what actually works in a real home environment rather than a commercial gym setting.
That grounded, practical perspective makes their take on adjustable dumbbells particularly useful for anyone in the UK weighing up their options.
First Impressions: Compact And Solid
Out of the box, the Stealth dumbbells make a strong first impression. The metal construction feels substantial without being unwieldy, and the compact cradle design means they take up significantly less floor space than a traditional dumbbell rack.
For home gym builders working with limited space — a spare room, a garage corner, or a garden shed setup — that compact footprint is not a minor detail. It is often the deciding factor. Keeping them stored at the right height on the Heavy Duty Dumbbell Stand V3 or Stealth All Out Stand V2 makes the setup even more practical.
Weight Range: 4kg To 41.5kg In One Pair
The Stealth system covers 4kg to 41.5kg per dumbbell — one of the widest ranges available in a UK adjustable dumbbell. That means:
- Light enough for mobility work, lateral raises and rehabilitation exercises
- Heavy enough for serious Romanian deadlifts, goblet squats and rows
- Enough range to grow with you over years of training, not just months
For most home gym users, this range removes the need for any additional fixed dumbbells. The Chrome Edition and Black Edition both cover the full range — the difference is in the construction of the adjustment mechanism.
Everyday Usability: The Twist Mechanism In Practice
The adjustment mechanism is a genuine selling point. Dial to your target weight, lift out of the cradle, train. Changing weights between sets takes two to three seconds — fast enough that it does not disrupt workout rhythm during circuits or supersets.
Level40FitnessUK's review highlights this as one of the practical advantages over pin-select or screw-lock systems, which can slow transitions and break focus mid-session. Adding Stealth Adjustable Kettlebells to the setup gives you the option of conditioning and swing-based work alongside your dumbbell sessions.
Value: What You Are Actually Getting
A full rack of fixed dumbbells from 4kg to 40kg would cost over £1,000 and require significant floor space. The Stealth system delivers equivalent range in one compact pair, backed by a two-year standard warranty with an optional lifetime upgrade.
For the price and footprint, that is a strong value proposition for any serious home gym builder. Browse all current pricing at assassingoods.com.

Frequently Asked Questions
What is the best adjustable dumbbell for a home gym in the UK? For most UK home gym users, the Stealth Adjustable Dumbbells from Assassin Goods are among the best available. The 1.5kg increment system, 4–41.5kg weight range and metal construction offer a combination that no major UK competitor currently matches at the same price point.
How much space do Stealth adjustable dumbbells take up? Each dumbbell sits in a compact cradle roughly the size of a standard dumbbell. A pair takes up significantly less floor space than even a small fixed dumbbell rack. For home gyms in spare rooms, garages or smaller spaces, the compact footprint is one of the key practical advantages.
Are adjustable dumbbells good for beginners? Yes. The Stealth system starts at 4kg and increases in 1.5kg steps, making it suitable for beginners who want room to grow without buying new equipment every few months. The fast adjustment mechanism also makes it easy to switch weights between exercises. See the Core Edition as an entry point.
How do I adjust the weight on Stealth dumbbells? Dial to your target weight on the handle, lift the dumbbell out of the cradle and train. The process takes two to three seconds. There are no pins to pull, no plates to slide and no alignment issues.
What is the difference between the Stealth Black Edition and Chrome Edition? The Chrome Edition uses fully metal construction throughout. The Black Edition uses replaceable nylon precision-fit inserts in the adjustment mechanism, which reduces noise and allows for part replacement if needed. Both cover the same weight range and carry a two-year standard warranty with an optional lifetime upgrade.
