Suitablesupport is provided for suspending the cylindrical outer shell from an upper supportmember, such as a ceiling. A generally cylindrical liquid-impermeable flexible liner is
provided within the outer shell for receiving and containing a liquid medium such aswater. The liner is configured and dimensioned to generally conform to the shape of theinner surface of the outer shell when the liner is fully expanded, such as when filled withwater. An intermediate layer is provided made of compressible material and arrangedbetween and contacting the outer shell and the liner when the liner is filled with liquid.The intermediate layer forms a cushion for absorbing external impacts to the outer shelland absorbs and attenuates shock waves imparted to the liquid medium within the linerto protect the liner and better simulate the feel of a conventional, non-liquid filled heavybag.
