An adjustable weight assembly includes a weight device and an adjustment device. The weight device includes a rail, a movable member and multiple weights. The movable member is connected to a rod and receives a force applied by a force applying unit so as to move along the rail. The rod has multiple through holes and each weight has a latitude hole and a longitudinal hole. Each latitude hole has a pin extending therethrough and the rod extends through the longitudinal holes. The adjustable device includes a driving unit, a movable part and multiple pivotal members. The driving unit drives the movable part and each weight is pivotably connected to one of the pivotal members. When the movable part moves along the rail, the pivotal member is pivoted to decide the engagement between the pin and the through hole so that the user can adjust the number of the weights.
