Abstract
An adjustable dumbbell includes a handle, a shaft rotatably engaged through the handle, a carrier attached to each end portion of the shaft and having an inner housing and an outer housing and one or more middle housings spaced from each other for forming two or more gaps between the housings and for engaging with weight members, and the inner housing and the middle housing each include a spring-biased projection extendible into the gaps for selectively latching the weight members to the handle and the shaft and the carrier, and a control device is rotatably engaged onto the shaft and coupled to the handle for actuating the spring-biased projections to latch the selected weight members to the handle and the shaft and the carrier.
