When you exercise, your heart doesn’t have much trouble pumping blood into your extremities. However, as the volume of blood it pumps increases, your veins may find it hard to keep up. That’s why strenuous activities like weightlifting can make your veins bulge out.
Sports compression socks help by gradually squeezing the muscles, moving blood out of overflowing venules into your deep trunk veins and up toward the heart. With this increased venous return, your muscles get more oxygen and nutrients. And with more oxygen and nutrients, they’ll be slower to fatigue and faster to recover.
