Abstract
An exercise dumbbell includes a handle and pairs of weights disposed on opposite sides of the handle and maintained in spaced relationship relative thereto. At least one latch is movable into and out of engagement with the weights to prevent movement of the weights in a first direction. At least one spring is connected to the at least one latch and operable in a second, discrete direction to encourage the latch to remain engaged with the weights.
