The invention discloses a
dumbbell group facilitating balance
weight adjustment. The
dumbbell group includes a storage seat and a
dumbbell; the dumbbell includes a
handle and two balance weight units, wherein each balance
weight unit includes a
brake cover, a rotation disc, an end disc, a plurality of hook discs, a plurality of balance weight blocks and a rotation limiting member; when the dumbbell is arranged on the storage seat, a
brake block on the
brake disc is pushed to slide to a releasing position, the
handle, the rotation disc, and the hook discs can rotate with respect to the brake disc, and then relative positions between convex portions and gaps of the hook discs and
hooking convex portions of the balance weight blocks are adjusted, each balance weight block is selectively arranged in each balance
weight space or released from the balance
weight space, and balance
weight adjustment can be achieved; when the dumbbell is away from the storage seat, the brake block slides to a brake position, and then the
handle, the rotation disc and the hook discs cannot rotate with respect to the brake disc, and the balance weight blocks in the balance weight spaces cannot be released from the hook discs; and in this way, the balance weight can be easily adjusted.
