An adjustable dumbbell pair that spans 17 weight settings from 5kg to 40kg per dumbbell.
The Pro Grade 40kg Adjustable Dumbbells replace a full rack of fixed weights using a twist-dial system that selects the target load in seconds. Each dumbbell covers 17 settings between 5kg and 40kg, and the dial locks only the chosen plates onto the bar while the rest remain seated in the storage tray. Both trays are included in the set.
The 17 increments are not evenly spaced, which reflects how resistance training actually progresses. Smaller gaps at the lower end, 5, 7, 9, 11, 13, 15kg, allow gradual load increases for isolation and accessory work where fine adjustments matter most. The steps widen through the mid-range and upper end, 18, 20, 22, 25, 27, 29, 32, 34, 36, 38, 40kg, matching the larger jumps that are practical for compound pressing, rowing, and hinging movements at heavier loads.

Twist-Dial Selection Mechanism
Rotating the dial at either end of the dumbbell engages the internal locking system, which secures the plates corresponding to the selected weight and leaves the remainder in the tray. The change takes a few seconds per dumbbell, with no collars, clips, or loose plates to manage between sets.

17 Distinct Weight Settings
The full increment list runs: 5, 7, 9, 11, 13, 15, 18, 20, 22, 25, 27, 29, 32, 34, 36, 38, and 40kg. This range covers warm-up loads, working sets, and top-end strength work without requiring any additional equipment.

Textured Anti-Slip Handle
The handle surface has a textured finish that maintains grip contact throughout sets. This is relevant at higher loads, above 25kg per dumbbell, where smooth handles can compromise control during pressing and rowing movements.

Included Storage Trays
Each dumbbell rests in its own tray, which holds the unloaded plates in place and keeps them off the floor between sessions. The trays also serve as the loading dock: the dumbbell is placed back into the tray to disengage the current setting before a new weight is dialled in.
Seventeen weight settings in the footprint of two dumbbells.
A rack of fixed dumbbells covering 5kg to 40kg in comparable increments would require roughly 17 pairs, occupying several metres of floor space. The Pro Grade pair sits in two storage trays and can be stored under a bench, in a corner, or inside a cupboard when not in use. The practical implication is that a full strength training programme from beginner loading through to advanced compound lifts becomes viable in a living room, spare bedroom, or any space large enough for a mat.
The dial system also removes a persistent friction point in plate-loaded training: the time cost of changing weights between exercises or supersets. Moving from a 15kg lateral raise to a 32kg bent-over row, for example, requires two dial turns rather than removing, reordering, and reattaching plates. For time-restricted training sessions or circuit-based programming where rest periods are short, this matters in practice.
Here is why the Pro Grade 40kg Adjustable Dumbbells is the best choice for our customers.
This pair was built for people who want a complete dumbbell range at home without the floor space, cost, or logistics of buying multiple fixed-weight sets. The 5kg to 40kg span covers beginner conditioning work, hypertrophy-focused programming, and heavy compound loading, all from a single product.
The dial adjustment is central to the product’s practicality. It makes it possible for multiple household members with different strength levels to train with the same pair on the same day, each selecting their own load per exercise without tools or setup time.
Here are 6 reasons we believe the Pro Grade 40kg Adjustable Dumbbells is the right fit for your household.
One Pair Covers 17 Weight Settings
From a single purchase, each dumbbell dials to any of 17 settings between 5kg and 40kg, removing the need for multiple fixed-weight pairs at different load points.
Weight Changes Take Seconds
The twist-dial mechanism selects and locks the target weight in a few seconds per dumbbell. There are no collars to thread, no plates to stack, and no clips to locate between sets.
The 5kg Starting Point Suits a Range of Users
A 5kg lower limit is light enough for shoulder isolation work, warm-up sets, and users earlier in their training. The same pair then scales to 40kg for heavier pressing and pulling exercises.
Storage Trays Are Included
Both trays come with the set, so the dumbbells have a designated resting position from day one. Unloaded plates stay organised inside the tray rather than loose on the floor.
The Increment Structure Matches Real Training Needs
The tighter gaps at the lower end of the range, where small load increases produce more meaningful adaptation, and wider gaps at the top, where larger jumps are workable, reflect how strength programming actually operates.
Multiple Users Can Share the Pair
Because weight selection is instant and requires no tools, two people with different working loads can use the same pair across a shared session without any meaningful setup time between turns.
Frequently Asked Questions
How does the dial mechanism lock the correct plates?
Rotating the dial to a target weight aligns an internal selector with the plate positions corresponding to that load. When the dumbbell is lifted from the tray, only the locked plates come with it. The remaining plates stay seated in the tray until the dial is moved to a new setting.
What is the process for changing weight mid-session?
Place the dumbbell back into its tray, rotate the dial to the new target weight, and lift. The tray must be used during any setting change because the plate release mechanism only functions when the dumbbell is correctly seated.
Can both dumbbells be set to different weights simultaneously?
Yes. Each dumbbell has its own independent dial, so one can be set to, say, 15kg while the other is set to 20kg. This is useful for unilateral exercises where each side works at a different load.
What exercises are practical at the 32kg to 40kg end of the range?
At those settings the dumbbells suit compound movements including Romanian deadlifts, single-arm rows, goblet squats, Bulgarian split squats, and flat or incline dumbbell press for stronger users. The textured handle is relevant at these weights, where grip security under load is more demanding.
Are the storage trays elevated off the floor, or do they sit flat?
The trays sit flat on the floor. If you prefer the dumbbells at a higher, easier-to-reach position, a dedicated stand can be added separately, but the trays alone are fully functional for storage and weight selection.
Is the set suitable for someone just starting resistance training?
The 5kg minimum per dumbbell is appropriate for most beginners on upper body accessory movements. As strength develops, the same pair supports progressive loading all the way to 40kg without any additional purchase.
