Image Number 2 for United States Patent #4357009.

A water-filled weight exercise bag having two compartments, one surrounding the lower leg and the other surrounding the foot, with a lace for retaining the bag in place, located under the foot and along the back of the leg. The adjustable lace allows the bag to be filled with differing weights of water to accommodate the particular weight required. The two compartments are connected by a portion for fluid communication there-between and which provide a hinge so that one of the compartments may be flexed out of the general plane of the other compartment.
