grasping the hand weight at a handle positioned in an opening extending through a central axis of the hand weight, the opening defined by a body of the hand weight;
applying a force in a first direction along an axis, wherein applying the force in the first direction comprises causing a movable mass to move in a second direction along the axis to deform one or more flexible membranes positioned around the central axis of the hand weight to deform in a second direction along the axis relative to the hand of the user and to shift a center of gravity of the hand weight along the axis in the second direction along the axis relative to the hand of the user; and
applying a torque in a first direction about the axis, wherein applying the torque on the hand weight in the first direction about the axis comprises causing rotation of the movable mass relative to the body of the hand weight in a second direction about the axis.
