1. A method of adjusting resistance to exercise, comprising the steps of:

  • positioning a plurality of weights in respective rest positions;

    moving a member into and out of alignment with the weights;

    moving a weight selector on the member along a linear path, including a first portion of the path that extends over an upwardly unbounded portion of each weight in a first subset of the weights, thereby leaving the weight selector free to move upward relative to the first subset, and a second portion of the path that extends beneath at least a portion of each weight in a discrete, second subset of the weights, to selectively secure the second subset to the member for upward movement together with the weight selector.
