An exercise device comprising interconnected, water-tight compartments which define a vest for supporting a fluid weight medium from the shoulders and about the upper torso of a human exerciser. Water or other fluid is removeably introduced into the water-tight compartments in variable amounts to weight the vest for use by the exerciser. Air is introduced into the compartments to occupy space not occupied by the water in order to fill out the vest. The air and water is expelled from the compartments to facilitate easy and light-weight transportation of the vest.
