Activity, such as walking and exercise is good for circulation. Circulation in the legs consists of two parts : arteries bring fresh blood to the legs, and veins drain the used blood out of the legs and back to the heart. The calf muscle pumps the venous blood up the leg; the one way valves in the veins prevent gravity from pulling the blood back down. While walking and exercise are excellent for overall cardiovascular health, they do nothing for the visibility of veins on the leg. The visibility of veins on the leg can be due to the way your body is built. In people with a low body fat content, the veins can be more visible. Think of professional body builders. Abnormal veins can bulge, but exercise won’t help that problem. Compression stockings can help control spider veins and bulging veins. A vein specialist can permanently eliminate bulging veins and spider veins.
