Bowflex SelectTech 552 vs CAP Barbell 150-lb Set

Space-saving tech vs old-school iron. One adjustable pair replaces 15 dumbbells, but is it as durable as the classic hex set?

The Verdict

For apartments or small home gyms, the Bowflex is unbeatable. But if you have the space and drop your weights, the CAP Barbell Hex set will last a lifetime longer.

Deep Dive Analysis

Adjustable dumbbells are complex machines. The Bowflex 552 uses plastic pins and gears to select weight. If you drop them, they break. Fixed Hex dumbbells are just chunks of iron wrapped in rubber. You can throw them through a wall and the wall will break first. Ask yourself: 'Am I gentle with my equipment?' If yes, Bowflex. If no, Iron.

Frequently Asked Questions

Do the Bowflex rattle?
They have a slight rattle compared to solid iron, but it's not distracting during standard lifts.
Is 52.5 lbs enough?
For most beginners and intermediate lifters, yes. For chest press or rows, you might outgrow them quickly.
