Overview

The BJDB52 is an adjustable dumbbell set made from alloy steel, sold as a pair (2 pieces) with a combined listed weight of 52 pounds and finished in black.

Adjustable dumbbells are meant to replace a rack of fixed-weight pairs with one set that changes load, and the 52 pound combined weight here sets the ceiling for how much resistance the pair offers together.

Who it's for

Suited to home gym users who want one dumbbell pair covering a range of weights instead of buying multiple fixed sets. Less suited to lifters who need to exceed a 52 pound combined load for heavier compound lifts.

Performance notes
