Expand your dumbbell options without expanding your footprint with the Loadable 15" Olympic Dumbbell Handles (pair). Inspired by Olympic barbells, each handle carries a 3.5" loadable sleeve and is built from rust-resistant steel with medium diamond knurling and bronze bushings for smooth rotation. Athletes load standard Olympic plates for lunges, squats, presses, and rotational core work — a space-efficient, commercial-grade way to add adjustable free-weight training to your floor.
