HAKENO Adjustable Dumbbells 15 in 1 Review UK 2026

Key specifications

Weight Range and Adjustment

Weight range and adjustment on these This adjustable dumbbells in 1 dumbbells cover up to 24kg per dumbbell. The set is described as variable weight and can be converted into a barbell for presses and rows. Weight changes are made by selecting the intended weight level for each dumbbell, then securing it for the lift. The listing's stated 40kg total corresponds to the pair at 2 x 24kg.

Build Quality and Materials

The build quality of the HAKENO in 1 adjustable dumbbells depends on the sturdiness of their adjustable weight mechanism and how well the locking system holds each selected setting during lifts. The set is rated up to 24kg per dumbbell, and it is marketed as converting to a barbell, so the materials need to withstand repeated press, curl, and row movements. Solid end caps and a secure selector area help reduce wobble. Heavy use can still reveal minor looseness if tolerances are tight, but the construction is clearly aimed at home durability.

Ease of Adjustment

With any 15-in-1 adjustable set, ease of adjustment comes down to how quickly the weight can be changed and how reliably the selected setting holds during a lift. For the adjustable dumbbells in 1 dumbbells, the listed range is 12/24/40kg, so moving between workout targets typically means stepping through those defined weight levels. A user generally checks the selected setting before gripping, then monitors for any unintended movement while exercising. When the locking feels secure, adjustments between sets can be carried out efficiently. Overall, stability of the chosen setting matters alongside speed.

Single or Pair and Value

Choosing between a single adjustable dumbbell and a pair largely depends on whether the workout needs one weight at a time or two weights moving together. With the HAKENO in 1 set, the value case is clearer because it is sold as 2x24kg, with a convertible barbell option that supports both single-arm work and paired movements. Using two dumbbells is typically better for squats, presses, and rows where symmetry matters. A single unit can support unilateral exercises, but it cannot match the full paired loads. Cost and space tradeoffs depend on training goals, since both options restrict and enable different variations.

Storage and Footprint

Storage and footprint matter because adjustable dumbbells need to fit around real living space. The adjustable dumbbells in 1 setup is designed to take up less room than keeping a full rack of fixed weights, targeting home training where space near the workout area is limited. The system stores when not in use, and it converts into a barbell within the same setup, which reduces the need for separate equipment. The usable footprint still depends on the clearance available for changing settings and for standing safely during lifts.

Comfort and Grip

Comfort and grip are key because these dumbbells will be held for sets of presses, rows, and lunges, and hand contact affects both control and how long someone can train without discomfort. The handle should sit securely in the palm to reduce shifting during rows, which can waste effort. If the grip feels too smooth, tighter wrist angles may be needed to maintain control. If the grip feels too rough, callus buildup can limit session length, particularly for longer workouts.

Who Are These Adjustable Dumbbells For?

These HAKENO adjustable dumbbells suit people who want one set to cover multiple exercises, particularly at home where space is limited. They are aimed at beginners and returning gym-goers who prefer variable weights rather than switching between separate dumbbells, with the set listed as 15 in 1. The maximum stated weight is 24kg per pair, with intermediate settings listed as 12kg and 24kg, and an additional setting of 40kg noted. This points to shoppers who want progression across those options, potentially including barbell-style training when converted.
