FlexLoad Adjustable Dumbbell Set: In-Depth Review

The FlexLoad Adjustable Dumbbell Set is our current top pick in the adjustable dumbbell category. This review goes into more detail than the summary on the buying guide on why.

Weight range and increments

At 5–52.5 lb per hand in 2.5 lb increments, the range covers everything from light isolation work through moderately heavy compound lifts, with small enough jumps to progress gradually rather than skipping past a weight that would otherwise be your natural next step.

The dial mechanism, in practice

Turning the dial to select a weight takes under five seconds, and lifting the handle locks the selected plates in automatically. The main adjustment period is learning to set the dial before lifting rather than after — picking up the dumbbell before the dial is fully seated can feel loose.

Footprint and storage

Each dumbbell has a molded storage tray. At maximum weight, each dumbbell is noticeably longer than a fixed dumbbell of the same weight — worth checking against your available space if you're tight on room.

Where it falls short

The top of the weight range (52.5 lb) is limiting for lifters who progress into more advanced strength training. It's also bulkier to hold than a fixed dumbbell at an equivalent weight, which some users notice on pressing movements specifically.

Editorial verdict

For a beginner or intermediate lifter building a first home gym, this remains our top recommendation in the category — the range and increment size cover realistic progression for a year or more, and the dial mechanism doesn't slow workouts down in practice.
