Abstract
A selector of a selectorized dumbbell comprises a keyboard having a plurality of keys that can be depressed into a weight selecting position. In this weight selecting position, a cam actuator on each key forces a pair of connecting pins apart to couple a particular weight to the handle. Preferably, to minimize the risk of accidental weight detachment from the handle, a pair of keys and two pairs of connecting pins couple each weight to the handle in a redundant fashion. The pins in each pair slide apart from one another to couple a weight to the handle and slide towards one another to uncouple a weight from the handle with the sliding motion of the pins being perpendicular to the axis of a hand grip of the handle.
