Abstract
Abstract To surmount a resistance a flywheel mass and a pulling member are mounted at one end of a shaft which is journaled in a housing of a gymnastics apparatus. The pulling or drawing member includes a rope which can be wound or unwound from the shaft. The rope has one of its ends fixed to the shaft end while the other end of the rope is attached to the housing and the main portion of the rope is guided over guide rollers housed in an independent handle which is pulled by a user.
