Abstract
First weights are disposed beneath a base member, and a selector rod is rotated into engagement with a desired number of the first weights. Second weights are disposed on opposite sides of a base member, and selector rods are selectively moved into engagement with the desired number of first weights. Various combinations of these arrangements may be used to provide adjustable resistance to exercise.
