Overview
A garage, spare room or home gym corner is where an adjustable set like this lives, trading a rack of fixed pairs for plates and a handle. The plates are cast iron, the handle has a rubber grip and the finish is black.
One set that changes weight saves space compared with many fixed dumbbells. The listing gives no plate sizes or collar type, lists nine items and nineteen pieces without a breakdown, and gives the handle diameter in an unclear unit.
Who it's for
Small spaces and mixed lifting routines suit an adjustable set with plates. Lifters who change weight often between sets, or who want fixed pairs, will find plate loading slow.
Pros and cons
- Cast iron plates
- Plate sizes not listed
- Collar type not listed
- Slower to change than fixed
- Handle diameter unit unclear
Performance notes
Cast iron plates are compact for their mass, and a rubber handle gives a firm grip when hands are damp. Changing weight means loading and securing plates, which takes longer than grabbing a fixed pair. Check that the collars are tight before every set.
