Abstract: A resistance device includes a resistance source, a winch, a draw rope, a pulley block, a wire management mechanism, a draw wire and a fixed plate. The output end of the resistance source is connected to one end of the winch, and the other end of the winch is pivotably connected to the fixed plate. The wire management mechanism is arranged between the fixed plate and the resistance source. One end of the draw rope is fixedly arranged on the winch, and the other end of the draw rope protrudes out of the wire management mechanism. A bobbin is convexly arranged at an end portion of the other end of the winch. The pulley block includes at least one fixed pulley and at least one movable pulley. The fixed pulley is fixedly arranged on the fixed plate, and the movable pulley is fixedly arranged on the wire management mechanism.
