Abstract:
1. A method of exercising comprising 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; wherein the rod includes opposing end sections each having a transverse cross section defining first, second, and third longitudinally-extending surfaces positioned circumferentially, and a detent between the second and third longitudinally-extending surfaces, and the at least one weight includes a hub defining a hole shaped to slide onto one of the opposing end sections; the hub including a bearing surface for slidably engaging the first longitudinally-extending surface and including at least one flexible finger with a tip extending radially inward within the hole, the step of assembly including sliding the finger along the second longitudinally-extending surface when in a first rotational orientation during assembly of the weights onto one of the end sections of the rod, and then flexing the finger over the detent and then interlocking the finger on the third longitudinally-extending surface when the weight is rotated to thus lock the weights onto the rod.
