This is actually the adjustable-height desk that pairs using a semi-recumbent elliptical trainer to let users physical exercise when on the job. Made to be pedaled at slower cadences that won’t break one’s concentration (or trigger one to break a sweat), a typical user can burn about 4,000 calories within a typical workweek. The desk’s height adjusts from 27″-47″ at the press of a button, allowing you to easily change to a favorite office chair or to work while standing. The elliptical machine’s generously cushioned seat slides smoothly across the frame to accommodate users of just about any stature, swivels for quick entry and exit, and it has a flexible backrest for comfort. Level of resistance is digitally controlled via the included performance monitor that tracks distance, watts, rpm, and calories burned, and displays information stored for up to 30 individuals on its 4″ x 6″ LED screen.
