An exercise apparatus having a trolley directly linked to the resistance weights. Bearings on the trolley react against the eccentric component of an applied force, while a selector bar connecting the trolley with the weights interacts with the weight stack to keep the trolley bearings in continuous contact with upright guide rods on which the trolley and weights ride when a user withdraws his controlled grip of the press bar or the lat pull down bar, removing any externally applied force.

An exercise apparatus, comprising: a frame support structure; at least one guide rod secured to the support structure; a plurality of resistance weights slidably disposed on said at least one guide rod; a trolley slidably connected by coupling means to the at least one guide rod for upward and downward movement, the coupling means comprising only two sets of rollers which sets are vertically spaced apart and are positioned only on opposite sides of said at least one guide rod; means for applying force to the trolley positioned on the same side of said at least one guide rod as the uppermost set of said rollers; and means for connecting the trolley to one or more of the resistance weights and for interacting with the resistance weights to help maintain the alignment of the trolley on said at least one guide rod.
