摘要： Exercising apparatus comprises a frame (2), a handle assembly (13,14) arranged to be grasped by a user and connected to the frame so that it can be moved upwards and downwards by the user to simulate weight-lifting exercises. A hydraulic piston and cylinder device (101) is connected between the handle assembly (13,14) and the frame (11) so that on upward movement of the handle assembly a piston (109.112) is moved in one direction in the cylinder (101) whilst on downward movement of the handle assembly the piston is moved in the opposite direction. The cylinder (101) is filled with hydraulic fluid and the piston (109,112) has passages (119,121,122) through which fluid flows from one side of the piston to the other during movement of the piston, and valve means (111) operable to restrict the total cross-sectional area of the passages when the piston moves in the said one direction, to increase the face required to lift the handles (13,14) against the resistance of the fluid and to open fully the passage means when the piston moves in the opposite direction to reduce to zero or a low value the force required to lower the handles. The piston is in two parts, one of which can be rotated relative to the other to vary the alignment between passages in one part and a series of passages of different cross-sections in the other part, to alter the total cross-sectional area of the passages thereby to adjust the resistance of the fluid to upward movement of the handles. The apparatus can be disassembled for storage or transport.
