What to look for
The four things that separate a good buy from a return.
Weight range and jumps
Check the lightest and heaviest settings and the size of each step, which decides how smoothly you progress.
Adjustment system
Dial, pin and plate-loaded designs trade speed against durability; owner reports show which ones loosen over time.
Handle and shape
Handle thickness and overall length affect presses, rows and how the weights sit on your body.
Space and storage
Adjustable sets replace a full rack of pairs; fixed sets need a stand and more floor.
