These adjustable dumbbells give you 20 weight settings per dumbbell, from 2kg to 40kg in 2kg increments, in one compact pair. The Stealth Core Edition is designed for effective home strength training without the space or cost required for a full rack of fixed dumbbells.
Quick Weight Changes
Select your weight by rotating the handle while the dumbbell is seated in its base. The twist-to-select mechanism lets you move quickly between exercises without manually adding or removing plates.
Use the same pair for curls, lateral raises, presses, rows, lunges, squats and Romanian deadlifts. You spend less time changing equipment and more time training.
20 Dumbbell Pairs in One Compact System
One Core Edition pair covers the same weight range as 20 pairs of fixed dumbbells. The included storage bases keep the plates aligned and organised while taking up a fraction of the floor space required for a traditional dumbbell rack.
The 2kg increments support controlled progression, while the 40kg maximum weight per dumbbell provides enough capacity for demanding upper-body and lower-body exercises.
Who Is the Core Edition For?
The Core Edition is the value-focused model in the Stealth range. It is particularly well suited to:
- People beginning strength training at home
- Lifters who want up to 40kg per dumbbell
- Home gyms with limited floor space
- Households sharing one adjustable set
- Buyers who prefer consistent 2kg weight increases
For different materials, adjustment increments and product features, explore the full adjustable dumbbells collection or use our adjustable dumbbell comparison to compare the Core with the Chrome Edition and Black Edition.
Serviceable and Supported
The Core Edition is engineered for long-term use with replaceable components and UK-based support. Core replacement parts are supplied through Stealth Support rather than listed for individual purchase through the online store.
For help identifying or replacing a component, visit our genuine replacement parts and support page.
Every pair includes a 24-month parts warranty. An optional lifetime warranty upgrade is also available for eligible structural and mechanical manufacturing faults, subject to the warranty terms.

All About Your Add-Ons
Stealth 8-16 kg
The Stealth Adjustable Kettlebell is a compact, space-saving training tool that replaces multiple traditional kettlebells with a single adjustable unit. Designed for home gyms and strength training environments, it allows athletes to quickly adjust weight using an internal plate system while maintaining the feel and balance of a traditional kettlebell.
Two models are available:
- Stealth 16: adjustable from 8 kg to 16 kg
- Stealth 24: adjustable from 16 kg to 24 kg
Both kettlebells adjust in 2 kg increments using removable internal plates, allowing precise progression for strength, conditioning, and kettlebell sport movements.
The solid cast-iron construction provides durability and consistent handling during dynamic movements such as swings, cleans, snatches, and presses. A flattened base allows the kettlebell to sit securely on the floor between sets.
Each adjustable kettlebell replaces several individual kettlebells, making it ideal for compact training spaces and home gyms.
- Adjustable weight system: internal plate design for quick weight changes
- 2 kg increments for progressive overload training
- Two weight ranges available: 8–16 kg and 16–24 kg
