ABSTRACT:
A counterweight exercise machine has a frame. The frame comprises two main guide rods; two sub-guide rods; a passive rod parallel to the two main guide rods; at least one main weight; a selector; a base having a lower substrate and an upper substrate; and two sleeves connected to the lower substrate and the upper substrate; at least one pin capable of passing through the round holes of the front sheet and the rear sheet and the passive rod; and at least one sub-weight. By above mentioned components, the selector serves to lock a predetermined number of main weights and the pin inserts into the sub-weight so as to increase the total weight. A force applied unit serves to drive the passive rod to drive the main weight and the sub-weight to operate along the main guide rods and sub-guide rods to achieve the object of training the muscle.
