The Premium Adjustable Dumbbells are a compact strength-training system that replaces a full rack of traditional dumbbells. Each dumbbell allows you to quickly adjust the weight using a twist-to-select mechanism, providing multiple weight settings in one unit.
The dumbbells use a twist-to-select handle system. When the dumbbell is in the base, you rotate the handle to choose your desired weight. Only the selected plates lock into the handle when you lift the dumbbell, allowing quick changes between sets.
The Core Edition Adjustable Dumbbells have a range of 2kg-40kg allowing precise progression as your strength improves.
The Core Edition has 19 2kg weight increments.
Yes. The adjustable weight range allows beginners to start at a lighter weight and gradually increase resistance as they build strength. More advanced lifters can use the heavier settings for demanding exercises.
These dumbbells can be used for a wide range of strength exercises including bicep curls, shoulder presses, chest presses, rows, lunges, goblet squats, tricep extensions and many more, making them suitable for full-body workouts.
Adjustable dumbbells replace a full rack of fixed dumbbells, saving significant floor space. A single pair can provide the equivalent of dozens of traditional dumbbells, making them ideal for home gyms.
Yes. The dumbbells are designed for regular strength training and are engineered with durable components to withstand demanding workouts when used correctly.
The dumbbells are designed for controlled strength training movements. They should not be dropped from height or thrown, as this may damage the adjustment mechanism or plates.
Each purchase includes a pair of adjustable dumbbell handles, the corresponding weight plates for your chosen model, and a storage base that allows safe storage and quick weight changes.
Yes. Adjustable dumbbells are specifically designed for home gyms where space efficiency and versatility are important. They allow you to perform a wide range of exercises without needing multiple sets of weights.
The dumbbells may produce a small amount of noise when placed back into the base or when plates are selected. This is normal and part of the adjustment mechanism.
Yes. The handles are designed to provide a secure grip during workouts to help maintain control during lifts.
Each model is designed with its own maximum weight capacity. If you expect to progress to heavier weights in the future, choosing the higher-capacity model is recommended.

All About Your Add-Ons

Heavy-Duty Stand

Unlike floor storage, the stand positions the dumbbells at a comfortable training height, reducing strain on the lower back when lifting heavy weights. The design prioritises stability and durability, making it suitable for regular strength training environments.

The V2 stand is purpose-built to match the Stealth adjustable dumbbell cradle design, ensuring a precise fit that allows quick racking between sets while keeping the plates secure during workouts.

Stealth FID Folding Bench

The Stealth Folding FID Bench V2 is a versatile adjustable weight bench designed for serious strength training while remaining compact enough for home gyms. The bench supports flat, incline, and decline positions, allowing a wide range of exercises including presses, rows, shoulder work, and core training.

The reinforced upholstery and high-density pads provide comfort and support, while the adjustable backrest and seat positions allow users to customise their lifting angles.
