Abstract

At least one latch is movable into and out of engagement with desired weight plates to prevent movement of the engaged weight plates in a first direction, and thereby secure same relative to the handle. At least one catch is connected to the at least one latch and operable in a second, discrete direction to encourage the latch to remain engaged with the weight plates.
