The MX55 Dumbbell System by MX Select

The MX55 Rapid Change Dumbbell System features our unique MX Select patented rack & pinion selection system: compact size, balanced feel and totally secure.

With the MX55 Dumbbell cradled you select the weight from 10-55 lbs (4.5-24.9 kg) at the turn of a dial. The selected weight level is locked into place as soon as the selector dial is pushed home.

The MX Select antimicrobial contoured handle offers surface protection against bacteria, mould & mildew, and other hazardous microbes.

One pair of MX55 Dumbbells replaces a 10-pair dumbbell set, taking up only one-tenth of the space. Safe, convenient, accurate and space-efficient, the MX55 Rapid Change Dumbbell System is a perfect addition to any home workout area.

The optional MX Dumbbell Stand elevates the Dumbbells to provide the sleek look of a professional training studio.

There is also an optional MX Select Adjustable Training Bench to further enhance your training space.
