Abstract
A selectorized dumbbell comprises a plurality of nested weights which have front and rear arrays of rails with the rails being vertically spaced from one another with a space beneath each rail. A handle is insertable into a gap between stacks of nested left and right weight plates. A selector comprises front and rear pin arrays in each end of the handle with the pins in these arrays being selectively movable in a horizontal direction into extended positions located in the spaces beneath the rails for coupling different weights to the handle. The pins in the arrays are movable into their extended positions by a single vertically movable member carried on a vertically rotatable shaft in the handle end or by a plurality of independently movable members in the handle end that are moved by a plurality of keys carried on a top side of the handle end.
