Overview

An electric leg exerciser powered by a 40 watt motor, weighing 11 pounds with a footprint of about 15 by 13 by 6 inches, finished in black.

The listing states a 50 pound weight capacity, which is worth double-checking against your own needs since it reads low next to typical adult-rated leg exercisers.
