Have you heard that the heart is your body’s circulation engine?
But what if we told you your calf muscles, especially the gastrocnemius and soleus, are just as vital?
These muscles are often called the “second heart” because they play a powerful role in venous return, helping blood travel from your legs back to your heart.
Every time you walk, rise on your toes, or flex your ankles, your calf muscles contract and squeeze the deep veins in your legs, acting like a natural pump. This movement keeps blood flowing smoothly, reduces the risk of swelling, varicose veins, and deep vein thrombosis (DVT), and supports overall cardiovascular health.
So next time you take a walk or stand on your toes, remember your calves are not just muscles; they are quietly working to keep your heart healthy and strong.
