Bowflex SelectTech 552 Adjustable Dumbbells
A complete dumbbell set for a home gym costs hundreds of dollars and takes up an entire room. Bowflex’s SelectTech 552 replaces 15 pairs of dumbbells in two compact units — and you can switch between 5 and 52.5 pounds in seconds.
Our Verdict
The Bowflex SelectTech 552s are the best investment for home gym strength training if you have limited space. The dial mechanism works reliably, weight changes take seconds, and the weight range covers the vast majority of dumbbell exercises.
What We Like
- Replaces 15 pairs of dumbbells (5-52.5 lbs) in two units
- Weight changes in 3 seconds with dial mechanism
- Compact storage footprint vs full dumbbell rack
- Weight range covers beginners to intermediate lifters
- 10-year warranty on dumbbells, 2-year on parts
Worth Knowing
- Larger and bulkier than fixed dumbbells at the same weight
- Dial mechanism requires precise engagement to work properly
- Not suitable for certain exercises like hammer curls above 30 lbs (too long)
Who Is This For?
Home gym users who want strength training versatility without space for a full dumbbell rack, apartment dwellers, beginners through intermediate lifters who want one versatile set, and anyone who does a mix of exercises requiring different weights.
The Full Picture
The SelectTech 552 mechanism uses a dial on each end to select weight from 5 to 52.5 lbs in 2.5 lb increments (up to 25 lbs) and 5 lb increments above that. Turn the dial, lift the dumbbell out of the cradle, and only the plates corresponding to the selected weight come with it. Return to the cradle, turn the dial, lift — different weight. The entire system works mechanically without electricity or complicated parts. Build quality is solid. The mechanism engages reliably as long as you set it down flat in the cradle before changing weight. Attempting to change weight with the dumbbell lifted causes the mechanism to stick — user error, but worth knowing. The weight range 5-52.5 lbs covers the vast majority of dumbbell exercises for most people. Beginners start at 5-15 lbs for most exercises. Intermediate lifters top out around 30-50 lbs for most movements. The 52.5 lb maximum is limiting only for advanced lifters doing specific heavy compound movements.
Bottom Line
The Bowflex SelectTech 552 is the pragmatic choice for home gym strength training. It’s not as satisfying as handling fixed dumbbells, but the space and cost savings are enormous — and it works.
