An apparatus for adjusting the rest height of free-moving weight-training machines in which a support plug is slidably inserted into one of several pockets in the upright standards of the weight-training machine. The plugs fit in pockets which are angled upward in the upright standards or, alternatively, the plugs extending out of the inclined standards at a 90 DEG angle, with the standards themselves inclined away from the user. The barbell used in the exercise rests upon the extended portion of the support plug in each upright standard and the rest height of the barbell can be varied by choosing one of several available pockets for containing the support plug in each upright support.
