An electromechanical device for simulation of physical exercise with legs and arms includes two pedals mounted on two contiguous pantographs, with parallel supporting arms that are positioned in a predominantly vertical sense, with an orthogonal junction and parallel arms which are articulated, in a predominantly horizontal sense, onto the frame of the device and which always move in opposing directions left and right, through traverses which are articulated on vertical and horizontal axles, respectively, connected to vertical and horizontal parallel bars by means of risers.
