Starling's law states that the heart's stroke volume increases in response to an increase in the volume of blood filling the heart, which is directly related to venous return. Venous return is indeed the volume of blood returned to the heart by the veins. Activities like walking enhance the skeletal muscle pump, which aids in increasing venous return. Breathing faster and deeper enhances the respiratory pump, which also increases venous return.
