Overview
This adjustable dumbbell kit is made of iron, totals 11.59 kilograms across the set, and ships as 21 separate pieces covering plates, handles and collars.
With 21 pieces making up roughly 25.5 pounds total, this reads as an entry-level starter kit rather than a heavy pair, since a single adjustable dumbbell in the 20 to 40 pound range already approaches that combined weight. Worth checking the piece breakdown against your target final weight before buying.
- Iron material
- 11.59 kilogram total weight
- 21 pieces in the set
- Adjustable plate-and-collar design
Who it's for
Suits someone starting out with adjustable dumbbells at a light total weight, more likely built as one dumbbell from plates than a matched pair. Not suited to lifters needing heavier loads without buying additional plates separately.
Strengths and trade-offs
Drawn from this product's published specifications.
- 21-piece set allows building different weight combinations
- Total 11.59 kilograms, about 25.5 pounds, is light for a full dumbbell set
- Generic brand naming makes it hard to cross-check against other buyer feedback
Performance notes
Iron plate-and-handle sets like this rely on threaded collars to lock plates in place. With 21 pieces total, assembling and swapping weight increments takes more handling than a dial-adjust dumbbell, in exchange for a lower cost per pound.
