Abstract
An adjustable-weight exercise apparatus include a rod with opposing end sections defining bearing surfaces, a first shallow channel without ribs, and a second shallow channel with ribs. The weights each include a hub shaped to telescopingly slide onto ends of the rod. Each hub further includes opposing flexible fingers with tips configured to slide along the second shallow channel when in a first rotational orientation during assembly of the weights onto the rod, and configured to flex over a raised detent into engagement with the second shallow channel between the ribs when the weight is rotated.
