A noiseless weight training machine is provided. The machine comprises a base frame mounted on a floor, a rectangular weight frame installed on the base frame, a pair of parallel guiding rods extending vertically from the base frame, a plurality of weight blocks for traveling up and down along the guide rods, a weight block connecting unit for connecting weight blocks of a number of interest to a user, a cable for suspending the weight block connecting unit through a sheave supported by the ceiling of the weight frame, and a shock damper placed beneath the weight blocks. The shock damper damps shock and vibrations generated by the impact of lifted weight blocks returning against the remainder thereof to reduce impact noise while exercising. The machine further includes elastic members disposed on stoppers mounted beneath the lowermost of the weight blocks so as to support them. The elastic members absorb minor shock occurring when the lifted weight blocks fall on the remainder thereof or when all of the weight blocks are lifted and fall on the stoppers.
