Bowflex SelectTech 552 (Single)

Overview

The Bowflex SelectTech 552 is the dumbbell that popularized the dial-adjust format, and offered as a single it lets buyers start with one or replace a lost half of a pair. One handle dials from 5 to 52.5 pounds across fifteen settings, with the early steps moving in 2.5-pound jumps that make it easy to add weight gradually on isolation work. The dials at each end turn independently to pick how many plates engage, and the block lifts cleanly out of its molded base once the load is set. The fine low-end increments and the wide range are why it remains a default recommendation for general home training. As with all dial designs you adjust only while the dumbbell sits in its base, and the molded plates and plastic shrouding favor cost and quiet over the industrial feel of steel-and-screw systems. Sold here as a single so you can match an existing one or build toward a pair over time. For straightforward, affordable adjustable weight with proven reliability, the 552 endures for good reason.
