ABSTRACT:
A weight lifting device, such as a dumbbell or bar bell, for exercise is provided with a handle to which a pair of fluid impermeable hollow chambers or containers are disposed at opposite ends for holding a weighting fluid. Each chamber has a sealable opening for accessing the interior of the hollow chamber and is provided with a plug for sealing the opening. A plurality of fluid displacement members are provided and are sized to pass through the sealable opening into the interior of the hollow chamber. The fluid displacement members displace a selected volume of the weighting fluid within the chambers so that the volume of fluid required to fill the chambers can be varied, thus varying the weight of the device.
