An exercise device comprises a bar, pairs of weights comprising weight collars which can be removably secured to either end of the bar, and a coupling for each weight collar. One of the bar or the weight collar has means for receiving a detent, e.g., a circular groove on an inner diameter of an axial central bore. A locking device is positioned in the other one of the bar or the weight collar. In arriving at a locked position, a spring-biased, axially disposed actuator pushes ball bearing detents, by camming action, radially outwardly through an aperture in the component housing the locking device to rest in a radially adjacent circumferential groove. The actuator is depressed to permit radially inward movement of the detents so that the weight collars caps can be removed.
