Abstract
A method of exercising includes steps of providing a rod and weights configured for self-attachment to the rod, assembling at least one weight onto each end of the rod, and securing the weights to the ends by rotating the weights on the rod from a first rotational orientation to an interlocking second rotational orientation. The weights have a hub defining a hole, an undulating outer surface for gripping, and inwardly-extending curved fingers with a slot around the fingers allowing the fingers to flex for frictionally engaging the rod when the weights are rotated on the rod.
