ABSTRACT:
A dumbbell includes a handle, a weight unit and two caps for retaining the weight unit within the handle. The weight unit includes weights and springs alternately arranged within the handle. Each of the caps is located against a related one of the springs so that the weights do not hit the handle axially.
