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

  • providing a selector rod with a shaft having a longitudinal axis, and with axially spaced members fastened to the shaft and extending radially away from the shaft, so that the shaft and the members are constrained to move together as a unitary part;

    providing a plurality of aligned weights with openings sized and configured to accommodate the shaft, and gaps disposed between adjacent weights to accommodate respective members;

    moving the selector rod downward into the openings in a manner which aligns each of the members with a respective one of the gaps;

    rotating the selector rod relative to the weights until respective members underlie desired ones of the weights; and

    moving the selector rod upward together with the desired ones of the weights.
