A compound weight system for use in exercising, or testing the human body includes upper and lower groups of weights normally resting on fixed supports, the weights in each group being, in the preferred embodiment, plates stacked one above the other and with the plates in one group having a different weight than the plates in the other group. Extending vertically through the weights for slidable movement relative to the weights is a connecting rod adapted to be connected at its upper end to a cable or chain which, in turn, may be connected to an exercise or testing device. In the preferred embodiment, the connecting rod has a series of apertures spaced along the length thereof and first and second keys are provided for selectively interconnecting any number of the weights of the first and second groups to the connecting rod such that the connected weights will move with the connecting rod in response to movement of the exercise machine. In one embodiment, the weights are held in alignment by means of fixed guide rods which extend vertically through the weights on opposite sides of the connecting rod and which guide rods are fixed so that the weights are movable along the guide rods by the connecting rod when the cable is pulled. Release of pressure on the cable allows the weights to descend along the guide rods. In another embodiment, the guide rods are eliminated and in place are used a plurality of projections on one surface of each of the plates and recesses on the opposite surface of each of the plates for receiving the projection on the next adjacent plate, the projections and recesses being complementary in shape.

A system of weights adapted to be moved against the force imposed by weights, the system comprising in combination: a first weight, a second weight spaced from and located below the first weight, a movable connecting member for moving one or both weights upon movement of the connecting member, first means for connecting the first weight to said connecting member independently of said second weight, second means for connecting the second weight to said connecting member independently of said first weight, and whereby movement of said connecting member serves to move any of the weights connected to said connecting member.
