The calf muscles—especially the soleus and gastrocnemius—function as a “second heart” by helping push blood from the legs back toward the heart.
When they contract, the veins are compressed, and one‑way valves ensure blood moves upward. This action supports venous return and prevents blood from pooling in the lower extremities.
If activity is limited, the calf pump weakens, increasing risks of DVT, varicose veins, and chronic venous issues.
Because the soleus muscle is well-suited for endurance, it is particularly effective at sustaining the pump over time.
Strengthening and stretching the calves—via exercises like calf raises and calf stretches—enhances their function, helping maintain healthy circulation, reduce blood pressure, and protect against clot formation.
