An exercising device has a frame, a seat, two pedals, a housing and an exercising mechanism. The exercising mechanism is mounted inside the housing and has a base, two brackets, a rotating axle, a torsion spring, a flywheel, a resistance device, a pulling rope and a first grip. The torsion spring is attached to the rotating axle. The flywheel is rotatably attached to the rotating axle in a unidirectional manner. The resistance device is mounted between the base and the flywheel to provide a resistance to the flywheel. The adjusting button is connected to the resistance device with a cable to adjust the resistance applied to the flywheel by means of rotating the adjusting button. The pulling rope reels around the rotating axle. The first grip is attached to the second end of the pulling rope.
