@tfchealth: Your calf muscles are often called your second heart, and there is a real mechanism behind it. Stand completely still and the pressure in the veins at your ankle sits around 90 mmHg. Walk about ten steps and it drops to roughly 22. That is your calf muscle pump pushing blood back up toward your heart. The soleus, the deep calf muscle, can also be activated sitting down. #calfmuscles #bloodcirculation #soleus #legday
