Overview

Peloton's PL-WT-B-03 is a pair of 3 pound cast iron dumbbells finished in black, sold as two pieces per the listing. It holds a 4.8 rating across 834 reviews, the highest rating in this batch.

Peloton sells its cast iron dumbbells across a range of weights, and the PL-WT-B-03 code here corresponds to the 3 pound pair rather than a heavier option, worth noting since Peloton dumbbell listings can look similar apart from the weight figure. Around 400 units were bought in the past month.

Who it's for
